• CloudFlare dashboards empty, or performance issues

  - by Katafalkas

  I wanted to test CloudFlare performance so I set my image gallery domain on it and started testing. I have added PageRules for caching. And chose the Security: Essentially Off. I checked NS check tools and they say that my domain name is propagated with CloudFlare. For testing purpose I created a link that loads 200 images from that server, and was using loads.in website to determine how much it is faster. After trying few regions, I noticed that there were no improvement in loading speed. So I looked up the dashboards, and it was empty. I am not sure if I am doing something wrong, or made some error in my setup, or it takes few days to start caching or working properly, but at the moment - after a day of testing - dashboards are empty. Also the NS check tools sais that all name servers are propagated to CloudFlare and working fine. So I assume I got a bad performance because it is simply not working. I sent a letter to CloudFlare support team, but did not get any straight answer. So essentially my question is: Anyone has any experience with CloudFlare ? How long does it take for it to start caching static content to CDN ? Or there is simply something I am doing wrong ?

• SQL Server performance on VSphere 4.0

  - by Charles

  We are having a performance issue that we cannot explain with our VMWare environment and I am hoping someone here may be able to help. We have a web application that uses a databases backend. We have an SQL 2005 Cluster setup on Windows 2003 R2 between a physical node and a virtual node. Both physical servers are identical 2950's with 2x Xeaon x5460 Quad Core CPUs and 64GB of memory, 16GB allocated to the OS. We are utilizing an iSCSI San for all cluster disks. The problem is this, when utilizing the application under a repeated stress testing that adds CPUs to the cluster nodes, the Physical node scales from 1 pCPU to 8 pCPUs, meaning we see continued performance increases. When testing the node running Vsphere, we have the expected 12% performance hit for being virtual but we still scale from 1 vCPU to 4 vCPUs like the physical but beyond this performance drops off, by the time we get to 8 vCPUs we are seeing performance numbers worse than at 4 vCPUs. Again, both nodes are configured identically in terms of hardware, Guest OS, SQL Configurations etc and there is no traffic other than the testing on the system. There are no other VMs on the virtual server so there should be no competition for resources. We have contacted VMWare for help but they have not really been any suggesting things like setting SQL Processor Affinity which, while being helpful would have the same net effect on each box and should not change our results in the least. We have looked at all of VMWare's SQL Tuning guides with regards to VSphere with no benefit, please help!

• Windows 7, network transmit (send) not working

  - by user326287

  My Win 7 works 2 years without problem. But now, I can't transmit (send) big data on LAN/Internet. I can: - Ping anything - Browse Internet, download files at full speed - Send e-mails with very small attachments. - Testing download speed on Speedtest.net, measure stable full speed. I can't: - Testing upload speed on Speedtest.net. Upload stuck.. - Save/send email messages with big (128k) attachment, independent from e-mail provider or e-mail box. THIS IS NOT A HARDWARE/CABLE/CARD OR OTHER NETWORK DEVICES PROBLEM! When I boot from a Linux Live CD, without ANY hardware change, all data sending, testing works correctly, at full speed. I have tried already in Win 7: - Disable Windows/3rd party Firewall completely - Reset IP stack parameters (netsh int ip reset c:\resetlog.txt) - Computer restore - Reinstall LAN driver When I inspect the packets in Wireshark in Windows, I see lot's of (maybe 60% of sent packets) "TCP Retransmission". Sometimes receive "TCP Dup Ack" or "TCP Out-of-Order". Linux don't do this. Thank you for the help.

• Slow Routing Over LAN (Wired)

  - by reverendj1

  I'm having issues with my router acting very slow (Adtran Netvanta 3458). We have two networks, let's call them A and B. When I run netperf from two servers on network A (no routing) I get speeds along the lines of 900 Mbps. Which makes sense, since we have all 1Gbps switches. When testing A to B (or vice-versa) I get speeds along the lines of 22Mbps. I have also tested connecting my laptop to the switchports on the router, and testing two servers on network A (no routing) and got speeds around 90 Mbps. Which makes sense since the switchports on the router are 100Mbps. Does anyone have any idea why routing would be so slow? We bought the router over a year ago, and we think it has been doing this since then, but we never actually tested it before. (network B isn't really used much, so we didn't notice much) We were implementing a site-to-site VPN and noticed it was ridiculously slow, so we started testing basic routing performance. I have ruled out cabling and router CPU/memory utilization. Adtran looked at my config, but didn't see anything wrong with it.

• cuda program on VMware

  - by scatman

  i wrote a cuda program and i am testing it on ubuntu as a virtual machine. the reason for this is i have windows 7, i don't want to install ubuntu as a secondary operating system, and i need to use a linux operating system for testing. my question is: will the virtual machine limit the gpu resources? So will my cuda code be faster if i run it under my primary operating system than running it on a virtual machine?

  I have seen various methods used when retrieving the value of a primary key identity field after insert. declare @t table ( id int identity primary key, somecol datetime default getdate() ) insert into @t default values select SCOPE_IDENTITY() --returns 1 select @@IDENTITY --returns 1 Returning a table of identities following insert: Create Table #Testing ( id int identity, somedate datetime default getdate() ) insert into #Testing output inserted.* default values What method is proper or better? Is the OUTPUT method scope-safe? The second code snippet was borrowed from SQL in the Wild

• Mouse movement / mouseover and JavaScript evaluation in watir

  - by Bilal Aslam

  I have a JavaScript-heavy Rails app which I am testing in watir. I have two specific testing requirements: I need to be able to simulate moving the mouse to a specific area of the screen (or at least triggering the onmouseover event for a div) Evaluating a snippet of JavaScript once the above has happened to see if a flag is set correctly I haven't been able to figure out how to do this in watir. Any ideas on how to do this?

• Windows Batch Scripting Issue - Quoting Variables containing spaces

  - by Rick

  So here's my issue: I want to use %cd% so a user can execute a script anywhere they want to place it, but if %cd% contains spaces, then it will fail (regardless of quotes). If I hardcode the path, it will function with quotes, but if it is a variable, it will fail. Fails: (if %cd% contains spaces) "%cd%\Testing.bat" Works: "C:\Program Files\Testing.bat" Any ideas?

• How to test UI interaction of Silverlight dialogs?

  - by Bernard Vander Beken

  I am using Silverlight 3.0 Unit Testing, version Silverlight Toolkit November 2009. Apart from unit tests, it allows to do UI interaction tests, typically using AutomationPeer subclasses (eg ButtonAutomationPeer to interact with a Button). Are there AutomationPeer classes to test the interaction with the following: OpenFileDialog SaveFileDialog MessageBox In unit tests it would be possible to stub these, but for integration and browser testing it would be great to have this testable.

• Can Hudson branch promotion get based on project stability?

  - by Wayne

  Hudson CI server displays stability "weather" which is cool. And it allows one project build to kick off based on the successful build of another. However, how can you make that secondary project dependent additionally on the stability of multiple builds of the first project? Specifically, project "stable_deploy" needs to only kick off to promote a version to "stable" if project "integrate" with version 8.3.4.1233 has built and tested successfully at least 8 times--in a row. Until then, it's still in integration mode. IMPORTANT: A significant caveat to this is that a single set of Hudson projects gets used as a "pipeline" to process each new version through to release. So a project may have built successfully 8 times in a rolw but the latest version 8.3.4.1233 may be only the 2 most recent builds. The builds prior to that may be an earlier version. We're open to completely reorganizing this but the pipeline idea seemed to greatly reduce the amount of manually project creation and deletion. Is there a better way to track version release "pipeline"? In particular, we will have multiple versions in this pipeline simultaneously in the future due to fixes or patches to older versions. We don't see how to do that yet, except to create new pipeline projects for each version which is a real hassle. Here's some background details: The TickZoom application has some very complete unit tests some of which simulates real time trading environments. Add to that TickZoom makes elaborate use of parallelization for leveraging multi-core computers. Needless to say, during development of a new version, there can be stability issues during integration testing which get uncovered by running the build and auto tests repeatedly. A version which builds and tests cleanly 8 times in a row without change plus has undergone some real world testing by users can be deemed "stable" and promoted to the stable branch. Our Hudson projects look like this: test - Only for testing a build, zero user visibility. integrate_deploy - Promotes a test project build to integrate branch and makes it available to public for UA testing. integrate - Repeatedly builds the integrate branch to determine if it's stable enough to promote to stable branch. This runs the builds and test hourly throughout every night. stable_deploy - Promotes an integrate project build to the stable branch and makes it public for users who want the latest and greatest. stable - Builds the stable branch once every night. After 2 weeks of successful builds (14 builds) it can go to "release candidate". And so on... it continues with "release candidate" and then "release".

• Creating IIS Instance over network using MSBuild

  - by Dan

  Is there a way to have MSBuild create an instance of IIS on another remote machine? I do the builds (which occur locally using TeamCity AFAIK), but would like the code to be pushed up to our testing server once the build is completed. I am using IIS 6.x (Windows XP dev and Windows 2k3 Server for testing).

  Does anybody have any experience going from ODP.net to devArt's dotConnect for Oracle? Some initial testing is showing Direct Connect in 64bit dotConnect running 30% slower at times than our original ODP.net/OCI 32 bit solution. Trying to determine if that's normal or if something may be wrong in my testing approach. Thanks!

• When should I opt for test driven development?

  - by VJ

  My question is same as the title. I have not done Test driven development yet,I have performed unit testing and I am aware of testing in general but I hear it is much advantageous to follow TDD?. So should I opt for it everytime or are there some preconditions... i just need to know some basic or important requirements when i should opt for TDD. Sorry if this question is too trivial.

• dynamic page caching- show redirected html cache page or show the dynamic page?

  - by i need help

  would like your comments. Eg: When user first visit www.testing.com/productdetailpage.asp I will use caching- store the whole page into productdetailpage.html When the user go to reopen productdetailpage.asp, user will be redirected to www.testing.com/productdetailpage.html It means they will see productdetailpage.html, not .asp Is this a good way? Any implication in terms of SEO and other part? Will it be better to read datas from .html into .asp and show the final page as .asp all the time?

• how to separate debug and release mode code

  - by john

  during debug mode or while i am doing testing, i need to print lost of various information, so i use this method ifdef TESTING // code with lots of debugging info else // clean code only endif // TESTING` Is this the good method, or is there any other simple and elegant method. But this way, I am repating the same code in two places and if anything is to be changed later on in the code, I have to do it in both places, which is time consuming and error prone. Thanks. I am using MS Visual Studio.

• Windows batch file timing bug

  - by elbillaf

  I've used %time% for timing previously - at least I think I have. I have this weird IF NOT "%1" == "" ( echo Testing: %1 echo Start: %time% sqlcmd -S MYSERVER -i test_import_%1.sql -o "test_%1%.log" sleep 3 echo End: %time% ) I run this, and it prints: Testing: pm Start: 13:29:45.30 End: 13:29:45.30 In this case, my sql code is failing (different reason), but I figure the sleep 3 should make the time increment by 3 at least. Any ideas? tx, tff
