Hello there,
I am running a webservice on IIS6, sometimes it runs at a reasonable speed, sometimes it runs painfully slow and sometimes inbetween. The application that consumes the service is vb.dotnet and runs on a local area network. Does anyone have any ideas? Where should I start to look? What could be causing this? Thank you for any help or ideas Kind regards John Sheppard

All of those things should be done. It may also be necessary to do the same sort of performance analysis that you would with any other sort of application. You may need to do profiling, look at performance counts, etc. -- -------------------------------------------------------------------------------- John Saunders | MVP - Windows Server System - Connected System Developer

Access is not a multi client solution and it could be an issue with speed. Access is not an Enterprise database solution. http://www.sql-server-performance.com/tips/asp_sql_server_p1.aspx http://www.aldex.co.uk/sqlupsizing.html If nothing else, SQL Server Express or MySQL are better solutions for an Enterprise solution if one doesn't have a production server running full SQL Server.

It will be used in both an intranet and internet environment. However at the moment it is just the intranet. I very much doubt its the intranet thats causing the problem. The server has 3 webservices on it. All different versions of the same one. Only one ever gets used at a time as I cycle them for versioning. I guess I should stop 2 of them and see if that solves the problem. The server should have the resources, it has 8GB ram, running Windows 2003 server (Im not sure of the processor, but its fairly beafy). It does have a terminal service client on it with approximatly 15 people attached to it running an access application, word and excel. It could be that it is just too overloaded because of the terminal services. The webservice connects to an access database. What I dont understand is why isnt it lightning fast say when running on my development computer. For example, on my AMD6000+, 4GB ram development computer, it doesnt run particularly fast (faster than the beefy server, but not a whole lot). The load there is just IIS and visual studio. Shouldnt that run lightning fast as there is no network to go through? (im sure this sounds increadibly newbish) Thank you so much for your advice, I should have listed those specifications in my original post. John

I have mucked with that and get some very strange answers. In pretty much all instances of trying this I essentially see as follows; A few seconds then a webservice output spike, then like 30 seconds later the thread ends and the data comes up in the GUI. Im so confused...I need to do more testing.. Im not actually using asynchronous calls either, the threading is all done manually...(i inherited the project like this)..hmmm i wonder if this has something to do with it... Would I be wiser testing on my development computer or testing on my production server? Thank you John
Sorry for so many posts...
Is bytes total per second on the webservice the appropriate counter to be using in perfmon? Thank you John
Sorry, yet another post...
http://www.careware.com.au/Webserver%20-%20Application%20login%20(3%20webservice%20calls,%202%20small%20ones%20and%20one%20that%20downloads%20a%20large%20cache).jpg Here is a image of perfmon, this was taken over about 6 minutes with 5sec intervals and is a capture of the application logging in, 3 calls are made to the webservice, 2 small, 1 large to download a cache.... Looking at this it makes me think that its my client application that has issues... There is currently very little load on the server because everyone has gone home... I dont get it :( Anyone got any tips on the correct counters to be using... Thank you for anyone who spends the time to look at this... John

Unfortunatly its not an option at this stage. We will be going to mySQL when we can. 6 months from now hopefully. What is actually currently perplexing me is that if I run the application in debug mode on my dev computer, it runs reasonably decently, not fast, but acceptable. As soon as I do it in release mode the perfomance drops in several orders of magnitude. Then when I deploy it, it seems to sometimes be slow and sometimes be mega slow. Sorry I know thats not exactly quantifying things well.... Could this be because one of the policy files is not being copied to the release or something like that, or an issue with compression. The screen shot posted, was from a deployed version running through ADSL 1500/256, with the server running on no load. Im showing my newbishness here as well with this question... The WSE, does that need to have the wse runtime installed on the client....i havent installed that on the client (I dont think thats the issue, but, because im having so much trouble finding the cause, im guessing theres 2 issues and im getting confused) Thank you MR Arnold for you ideas, I will look into the MS-Access and see if thats causeing the issue...hmm although if it was.... wouldnt my local network connection just hmmm..fuck i need to take a break from this i think....start from scratch... Thanks heaps Mr Arnold for your ideas and help...very much appreciated... John
<snip>
I *think* i have found the problem... Its not actually a webservice issue at all :( It has something to do with a few dll's im using on the client side. I deleted everything from my bin and obj directories and its runs approximatly 70% faster. Still slower than I would like, but scraping in as acceptable. It now runs properly on my machine, but when I deploy it on another computer...its slow again :( But at least I now know to put my energies into exploring elsewhere. Im not sure where, but im guessing its some kind of dll regestering problem or something...not sure... Thanks so much for spending your time helping me Mr Arnold Very much appreciated John Sheppard

Hmm, ok I tell a lie, it is kinda a webservice issue... It has something to do with inputtrace.webinfo and outputtrace.webinfo...if i copy those to the deployed directory things speed up immensly... Im not sure what these do, Im looking at that now! Hope this helps someone, somewhere.. John

As to why this was happening. Im not sure, but I'm content to have it turned off as I dont need it. John
