Slow performance with Windows XP

Slow performance with Windows XP

Slow performance with Windows XP

(OP)
We have a software product that is developed in Clarion.  It is mature product that runs on Windows 95 and higher.

One process when running this application (disk intensive process creating files) takes about 15-20 minutes on Windows XP instead of less than minute when using Windows ME or Windows 98

We have lots of users of the software.  It primarily happens on Windows XP although on one occasion one of our users indicated it took this performance hit on Windows 2000
I have some users who are using Windows XP who are not having problems but most are.

What could the issue be?

Our end users are very frustrated.

Is there a registry entry that we need to chang.

RE: Slow performance with Windows XP

I haven't used Clarion on Windows XP that much.  I have a couple of suggestions that are no cost.  1. Check the memory on the machine that is running slow and compare it to the systems that are not having the problem.  2. Try running the application in compability mode on the machine running slow.

I hope this narrows your search for a solution.

RE: Slow performance with Windows XP

Check: Opportunistic locking, anti-virus software, cache settings ...

RE: Slow performance with Windows XP

Hi, any ideas of what is wrong ?
I have the same issue...

Help !!!

RE: Slow performance with Windows XP

I have 130 Windows XP work stations running a number of Clarion applications.  They run faster on XP then they did on any other Windows OS.

I think that if you have an application compiled on an older version (prior to C55H) of Clarion you might have a problem though.

Have the application recompiled using at least Clarion version 5.5H and you should be fine.

I run with a number of anti-virus checkers just fine.

RE: Slow performance with Windows XP

I also have notice older Clarion (in my case ancient 2.003) apps run noticably slower on Win2000 and somewhat slower on XP

We are looking at moving on up to 5 or 6


Good Luck

RE: Slow performance with Windows XP

I had the same issue with 2k two years ago, I solved it by using STREAM in my procedure... it worked fine. I think it is because the 2k/xp disk cache does not work as the 98/me.

RE: Slow performance with Windows XP

Hi,

Maybe if you use stream() it will be faster, it worked for me.

Hi,
If you are using TCPIP - Check your MTU settings.

I am using Clarion with TPS database on Win98, NT4, Win2000 and XP on a TCP/IP network and experienced a problem similar to yours when using XP.

The following is a summary of default MTU sizes for different network media.
    Network                  MTU (bytes)
   -----------------------------------
   Ethernet                   1500
   IEEE 802.3/802.2           1492
   PPPoE (WAN Miniport)       1480
   X.25                        576

Goto this link for details: http://help.stargate.net/broadband/mtu.shtml
 
You can check your MTU setting using the DOS Ping Test: http://help.stargate.net/broadband/mtu_ping_test.shtml

For Windows 95, 98, ME and NT 4.0 - use the Freeware GUI utility DrTCP. It is available for download at http://www.dslreports.com/front/DRTCP021.exe.

Note: If have XP on a laptop (ie .Office/Home), it may pay to check your MTU values at each location and set to the lowest value.

Cheers..
