Hi
We are experiencing a performance problem when communicating with the active directory using System.DirectoryServices. DirectoryEntry.Invoke("SetPassword", new object[] { password }) sometimes takes 15 seconds. The Service that makes the call is running on the same machine.
What could make it that slow?
Cheers,

Hello !
I made some searches on Google, and I read some posts, articles and benchmarks about Ruby on Rails being slow and I am planning to build one website that will have a good amount of users inserting data and there will be some applications to process this data (maybe in Ruby, you can help me choosing the language).
What is the real performance of Ruby on Rails with large traffic ?
Thank you !
My application compiled in .NET 4 seems to be performing really slow compared to .NET 3.5. When I did the performance analysis, I found out that the System.Math libraries in VS2010/.NET 4 have slowed down considerably.
Any explanation to this? Has anyone else come across this or am I the only one seeing this?
Thanks,
Niranjan
How can I speed up the scrolling of UserControls in a WinForms app.?
My main form has trouble scrolling quickly on slow machines--painting for each of the small scroll increments is CPU intensive.
My form has roughly fifty UserControls (with multiple fields) positioned one below the other.
I’ve tried intercepting OnScroll and UserPaint in order to eliminate some of the unnecessary re-paints for very small scroll events, but the underlying Paint gets called anyway.
How can I streamline scrolling on slower machines?
I have application that brings response via Ajax and creates 5-20 new jQuery click listeners on each refresh. Both IE and mozilla browsers seem to be slowing down with usage. Can this slow down browser performance significantly. Can listeners be "released"?
Hi,
Javascript is running extremely slow on IE on some pages in our site.
Profiling seems to show that the following methods are taking the most time:
(Method, count, inclusive time, exclusive time)
JScript - window script block 2,332 237.98 184.98
getDimensions 4 33 33
eh 213 32 32
extend 446 30 30
tt_HideSrcTagsRecurs 1,362 26 26
String.split 794 18 18
$ 717 49 17
findElements 104 184.98 14
What does "JScript - window script block" do?
We are using jquery and prototype.
Thanks,
I've developed a GPS app in which i record the user roots and show it
on the map.......but
Panning around on the map when reviewing my route is painfully slow,
it takes at least 4 or 5 seconds for the map to respond the finger
swipes......
I've overridden the onDraw() method and drawing the lines to show the
routes......is there any better way to do this so that panning becomes
faster as in "MyTracks"...........
Thank you all.....

i have a simple update query (foo column type is BOOLEAN (default false)):
update tablename set foo = true where id = 234;
which "id" is set to (primary) key, and if i run "explain analyze" i got:
Index Cond: (id = 234)
Total runtime: 0.358 ms
but still, i have plenty of unexplained queries at slow log (pgfouine), which took more than 200s (?!):
Times executed: 99, Av. duration (s): 70
can anyone please explain, whats the reason for that? (1.5 mio rows in table, postgresql 8.4)
My slow query log is full of entries like the following
# Query_time: 1.016361 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0
SET timestamp=1273826821;
COMMIT;
I guess the set timestamp command is issued by replication but I don't understand how set timestamp can take over a second. Any ideas?
Whenever I run rspec tests for my Rails application it takes forever and a day of overhead before it actually starts running tests. Why is rspec so slow? Is there a way to speed up Rails' initial load or single out the part of my Rails app I need (e.g. ActiveRecord stuff only) so it doesn't load absolutely everything to run a few tests?

I load the embedded browser into java and have it load a page.
It seems to load really slow... is this an issue with the page caching? What can I do to speed this up?
hi, I'm using jquery-plugin columnizer
http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=columnizer
for this website: http://donatellabernardi.ch/drupal
It is sometimes very slow to create the columns (you can try changing the browser window size, or selecting a filter.
Sometimes Firefox gives the error message: "Unresponsive Javascript script" and I have to press on continue to continue the navigation.
thanks
hi,
I'm using columnizer plugin (http://welcome.totheinter.net/columnizer-jquery-plugin/) to update my pages and display elements in vertical columns.
It usually takes 2 seconds to update the view. Is that normal ? It seems to be quite slow.
I sometimes receive Firefox message (Unresponsive javascript)
thanks
When I submit a form, I can see my browser's progress bar slowly increased, it takes 4-6s to submit a form.
It was a generic form like :
<form id="someid" name="someName" action="someAction.do">
...
</form>
I test it in IE8 and Firefox 3,both are very slow.
My network condition is fine, my server works great.
What could be the problem?
I noticed that WPF application startup is sometimes pretty slow. Does anybody know if the the cause is the elements initialization or DLLs loading or something else?
I have tried using the My.Computer.Network.DownloadFile method but unfortunately it is slow.
Executing the simple command below takes ~5-10 secs, which I would say is a lot longer than expected for downloading a 9 kb file.
`My.Computer.Network.DownloadFile("http://www.google.dk", "j:\temp\test.html")`
I am connecting via a high-speed connection (10GB) from a Win7 machine. Do anyone know of any explanations for this behavior?
Hope that you can help me out with this.

Hello,
I am new to SVN. I want to check out a very large project over a slow connection which takes ages to download. I have zipped versions of project on both remote server and my local which are identical. Is there an easy and quick way to sync my local project with remote server without a full checkout?
Thanks
I guess I am not saying it right in the title.
What I intend to do is to hook to some system api,like a time interrupt happens every amount of time (which is how every application in the operating system interprets time) and make an application's call to this api return some bigger/smaller result. So from the point view of an applicaiton, time has been speed up or slow down.
I have found some application on windows doing this, can anyone gives me some pointers on how to implement this on Mac OS X?
I use the following code to log a map, it is fast when it only contains zeroes, but as soon as there is actual data in the map it becomes unbearably slow... Is there any way to do this faster?
log_file = open('testfile', 'w')
for i, x in ((i, start + i * interval) for i in range(length)):
log_file.write('%-5d %8.3f %13g %13g %13g %13g %13g %13g\n' % (i, x,
map[0][i], map[1][i], map[2][i], map[3][i], map[4][i], map[5][i]))
Is it true that interfaces slow down programs? I have heard that this is the case because during running time each during each usage of an object implementing this interface the decision has to be made which class implementing the interface this object belongs to.
I am especially interested in an answer for C++, but also in general. And if this is true, some numbers would be helpful, too.
Thank you very much!
I have a web site that displays a column of flash videos. The page is w3c-valid.
The problem is that the page loads very slowly and sometimes crashes my web browser. Until the page is fully loaded, the videos are slow to respond and play. Is there a way to make these videos load their preview images only? What should I do to speed the page up?
The videos are 360x264.
Hi guys.
I read about function pointers in C
And everyone said that will make my program run slow.
Is it true?
I made a program to check it.
And I got the same results on both cases. (mesure the time.)
So, is it bad to use fuction pointer?
Thanks in advance.
I'm trying to use Eclipse + PyDev for studying OpenGL programming but when I type
from OpenGL.GL import *
from OpenGL.GLUT import *
IDE becomes extremely slow!
Ok. It isn't a smart idea import to much useless things but it's so useful for learning a new library!
Any help?
PS: I use Ubuntu with Eclipse Galileo.
We are using utl_file in Oracle 10g to copy a blob from a table row to a file on the file system and when we call utl_file.fclose() it takes a long time. It's a 10mb file, not very big, and it takes just over a minute to complete. Anyone know why this would be so slow?
Thanks
