All
We are having a severe performance problem with Powerbuilder v6.5.1 PFC
connecting to SQL server 7 running over citrix.
When running in a true Client Server Environment we get a 1.5 second
response to open a complex tab page retrieving +- 500 rows of assorted
data from different sources.
When we install the same application onto Terminal server the response
goes to a staggering 15 Seconds to open the same window for the same
customer.
Our Terminal server Box is a
IBM Netfinity
Twin Piii 500 MHZ
1.5Gb RAM
We have monitored the performance of the Netfinity Box and there is no
obvious resource issues and the processors are hardly been used.
Does someone have any ideas as too what could be causing this bad
performance issue ??
Thanks in Advance

We found by adding your application into the registry that the terminal
server would not sleep changing out reponse time from 15seconds to 2.2
seconds.
This is what's required to change.........
In the registry
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Terminal
Server\Compatibility\Applications\<YOUR APP in Capitals>
Add the following values
Value Name : Flags
Data Type : REG_DWORD
Value : 0xc
Value Name : FirstCountMsgQPeeksSleepBadApp
Data Type : REG_DWORD
Value : 0xff
Value Name : MsgQBadAppSleepTimeInMillisec
Data Type : REG_DWORD
Value : 0x0
Value Name : NthCountMsgQPeeksSleepBadApp
Data Type : REG_DWORD
Value : 0xff
The above solved all of our terminal server performance problems...
Hope it helps someone else out there having the same problems as we
were..................
