  • Assignment to LAN queues (qWAN1 & qWAN2) from dual-WAN in pfSense

    - by Kurian
    I need help creating floating rules in pfSense for the following: I have two upper limited download queues qWAN1 and qWAN2 on my LAN interface. Each has its own qACK1, qDefault1 etc. How do I assign all unclassified traffic from WAN1 to LAN->qWAN1->qDefault1 and from WAN2 to LAN->qWAN2->qDefault2. qLink is the one and only default queue on LAN so that I get wire speed to the pfSense host from the LAN.

  • Subversion/Hudson/Sonar/Artifactory - too much for my little server to handle! Help!

    - by Ricket
    I have a little dedicated server. It's at a cheap price and has a simple AMD 1800+ (1.5ghz), 256mb DDR RAM, ...need I continue? And I think I'm overloading it already. I have installed the following, and it's running CentOS 5.4: Webmin Apache MySQL Subversion as an Apache module Hudson (standalone) Sonar (standalone, runs with a standalone Jetty install) Artifactory (standalone) That's pretty much it. But I'm having problems; pages are loading quite slowly. Network speed of the server is excellent, but I think I'm just running out of CPU and/or memory. A side-effect of the pages loading slowly is that sometimes Hudson times out, not being able to start Maven or contact Sonar in a certain amount of time. I think the next step to speed things up might be to move to an application server and use the WAR version of Hudson, Sonar and Artifactory together on that server. I don't know that it will help, but it just seems to make sense, especially with Sonar running on its own Jetty install and the other two probably running their own mini application servers as well. Am I correct in thinking this? Is this the right course of action? Any other tips on how to make the server run faster? I can post more data if you'd like, just let me know what else would help you answer my question. Oh, also just to cure any suspicions, I don't have any sort of virus or spyware. I protect my SSH access with DenyHosts (which has blocked 300+ brute forcers in the past few months), and I have confirmed that the top four processes in terms of memory and CPU usage are Sonar, Artifactory, Hudson, and MySQL. Edit: I just thought of another thing that I'd like you to comment on as well: Apache currently has 8 spawned slave processes, taking 42MB of ram apiece. This is not my web server. Is everything else able to function if I shut down Apache? Can you point me towards a tutorial or something on migrating Subversion from Apache into something that might work along with the other three applications, maybe even make Subversion a WAR file or something?

  • ruby on rails gitorious setup on ubuntu

    - by dogmatic69
    Ive been trying to install gitorious for a while now which required ruby and rails etc. Ive finally got rails pages serving but cant finish the installation of gitorious because the gem version is too new. the error logs say please run 'rake ultrasphinx:configure' and that gives rake ultrasphinx:configure (in /var/www/apps/gitorious) rake aborted! uninitialized constant ActiveSupport::Dependencies::Mutex /var/www/apps/gitorious/Rakefile:10:in `require' (See full trace by running task with --trace) From searching google this is beacuse of the wrong gem verison. Cant find a way to down grade it. apparently sudo gem update --system 1.4.2 should do the trick but ubuntu 10.10 does not like this. ERROR: While executing gem ... (RuntimeError) gem update --system is disabled on Debian, because it will overwrite the content of the rubygems Debian package, and might break your Debian system in subtle ways. The Debian-supported way to update rubygems is through apt-get, using Debian official repositories. If you really know what you are doing, you can still update rubygems by setting the REALLY_GEM_UPDATE_SYSTEM environment variable, but please remember that this is completely unsupported by Debian. So i added export REALLY_GEM_UPDATE_SYSTEM=1 to .bashrc and reloaded it with . ~/.bashrc and still the same. ive tried various forms of setting this environmental variable with no luck. Ive also been told on #gitorious irc channel to add the file config/initializers/rubygems.rb with the line require "thread" to it. This has done nothing. EDIT: Just found another way which was rvm install rubygems 1.4.2 and it gave: Removing old Rubygems files... Installing rubygems dedicated to ruby-1.8.7-p334... Retrieving rubygems-1.4.2 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 288k 100 288k 0 0 282k 0 0:00:01 0:00:01 --:--:-- 414k Extracting rubygems-1.4.2 ...

  • How to get the installed Memory Type

    - by balexandre
    Windows 7 could be better at this, it tells everything about the computer CPU but only the Memory amount Microsoft should add information about DDR type, speed and maybe CL as well. While this never happens, What's the best and easy way to check the installed memory so we can buy and upgrade it? I was thinking a simple software so I don't need to install the full SiSoft Sandra for example, just looking for something small, only for the memory part.

  • methods for preventing large scale data scraping from REST api

    - by Simon Kenyon Shepard
    I know the immediate answer to this is going to be there is no 100% reliable method of doing this. But I'd like to create a question that details the different possibilities, the difficulty of implementing them and success rates. I would like to go from simple software ip/request speed analysis to high end sophisticated soft/hardware tools, e.g. neural networks. With a goal of predicting and preventing bogus requests and attempts to scrape the service. Many Thanks.

  • How to permanently save power options in windows 7

    - by Ieyasu Sawada
    How can I set the hard disk to never turn off permanently?And the sleep to never, together with the hibernate. Because the options resets to their default values when I turn off, log off or restart my computer. I am using granola on my laptop and it is set to lowest speed. When I restart it turns to full power again. Does it have something to do with the power options resetting to their default values?

  • How can Rackspace beat DigitalOcean's Pricepoint? [on hold]

    - by Matt Jensen
    I have recently discovered Digital Ocean and I have found it to be a relatively nice experience for small staging servers, and the thought occurred to me, why am I paying $267~ for a server on Rackspace (40GB RAM, 160 GB Drive, 2 vCPUs, 400 Mb/s) when Digital Ocean offers a server for $40 (40 GB RAM, 60GB Drive [storage is not a concern of mine], 2 vCPUs, ?Mb/s)? Does Rackspace offer some kind of obvious advantages in Transfer speed/bandwidth? My applications are small startups that for the immediate future will only have about 200-300 concurrent users at once.

  • Why should I choose either PCL or PS when both are supported

    - by Goyuix
    Obviously the answer depends to some degree on the various versions supported, but in general terms - is there any reason I should pick one over the other? PCL for art and PS for text? Does one typically require less RAM on the printer? Speed differences? For home use it doesn't matter and only professional print people will notice and care?

  • How to install Dvorak Type 2 (ii) German on Ubuntu using Gnome

    - by Peter Lustig
    Currently I am using standard Dvorak on Ubuntu 13.10 and Gnome 3.10. Unfortunately, writing Umlauts (ä,ö,ü) in German requires me to switch to QWERTY/QWERTZ frequently or forces me to not write those umlauts (which looks strange to German native speakers). Is there a way to use Dvorak Type 2, including the umlauts, but otherwise using the standard English layout on Ubuntu with Gnome? I'm a fast typer on standard English Dvorak and would like to avoid fully switching to German Dvorak as this would (at least temporarily) reduce my typing speed.

  • Disable scroll acceleration (windows/lenovo)

    - by dhardy
    Exactly the opposite of http://superuser.com/questions/101482/global-scroll-acceleration-in-windows, is there a way to disable scroll-accelartion on windows (touchpad -- maybe from lenovo drivers). It's heck of annoying -- using no accelartion but high sensitivity like on linux is so much more precise. ( With this silly acceleration, I either have incredibly slow scrolling, or scrolling so fast it skips whole chunks of text at once. Speed control but not acceleration control. Could say the same for mouse cursor, though that's less annoying. )

  • Problem with slow hard disk

    - by Makis Arvin
    We bought some new PCs in my company with the new iCore 7 and 8GB memory and the following hard disk: WESTERN DIGITAL WD8000AARS 800GB CAVIAR GREEN SATA2 The problem we have is that after installing windows XP64 SP2 the write speed of the hard disk is extremely low!. The windows system monitor shows that the Average Disk queue length is always at 100% and a winzip extract of 350mb takes about 8min. Is there any idea on where to start looking for the cause of that? Thanks

  • Poor performance of single processor 32bit Windows XP xompared SMP in VBA+Excel

    - by Adam Ryczkowski
    Welcome! On many computers I experienced poor performance of 32 bit guests running on 64 bit Linux host (I used only the Debian family). At last I managed to collect benchmark data. I made the benchmark by running custom VBA macro, (which we use in our company) that generates 284 pages long Word document full of Excel Pie charts, tables and comments. The macro is run as a single task (excluding the standard services) on a set of identically configured Windows XP 32-bit systems. I measured the time (in sec.) needed to perform the test. The computer (i.e. my notebook Asus P53E) supports both VT-d extensions and native Windows XP. It has 2-core processor, each core is hyperthreaded, so in total we have 4 mostly independent execution units. I use the latest VirtualBox 4.2 and VMWare Workstation 9.0 for Linux, installed together on the same host (running Mint 13 Maya) but never run simultaneously. The results (in column Time) are no less accurate than ± 10% Here are the results (sorry for the format, but I couldn't find out a better solution for tables in SO): +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ | Host software | # processor | Windows kernel | IO APIC | VT-x/AMD-V | 2D Video Accel | Time | +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 1 | 0 | 1139 | | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 1 | 1 | 1050 | | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 0 | 1 | 1644 | | VirtualBox | 4 | ACPI Multiprocessor PC | 1 | 1 | 1 | 6809 | | VMWare | 1 | ACPI Uniprocessor PC | | 1 | 1 | 1175 | | VMWare | 4 | ACPI Multiprocessor PC | | 1 | 1 | 3412 | | Native | 4 | ACPI Multiprocessor PC | | | | 1693 | | Native | 1 | Advanced Configuration and Power Interface (ACPI) PC | | | | 1170 | +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ Here are the striking conclusions: Although I've read in the VirtualBox fora about abysmal performance with 32-bit guest on 64-bit host, VMWare also has problems compared to native run, still being twice faster(!) than VBox. Although VBA is inherently single-threaded, the Excel calculations, which take much more than a half of total computation time, supposedly aren't. So one would expect some speed gain when running on 2+ cores ("+" for hyperthreading). What we see is a speed loss. And quite big one too. For the VirtualBox the VT-d extension isn't a big deal. Can anyone shed some light on why the singlethreaded Windows kernel is so much faster than the SMP one?
