Hello,

I am investigating some latency issues I've been experiencing, and I've 
narrowed one of them down to the creation of new threads. I use the 
tdlaunchpad from the TopDown library, but basically I'm finding that when 
creating a new thread, there often times is a 10-15 second delay. The line 
of code that is executing when the delay occurs is:

oThread := Thread():new()    create new thread object


Does anyone have a reason why this might occur? It seems to run quickly on 
my laptop when running in a stand-alone mode, but I see the long delays when 
running across the network when multiple users are logged in.


Thanks,

Scott

which Xbase++ Version are you talking about ?

Hello Everyone. This problem is still happening...and its being particularly 
bad today. Its taking 15-20 seconds in some cases between the time the new 
thread creation begins and when it completes.

Any other suggestions on what might be causing this to happen?

Thanks!!

hi,

> Hello Everyone. This problem is still happening...

i don't think that Thread() itself is the Problem ... try a small Demo.
most it is the Environment so give us more Information

Anti-Virus ?
where is your EXE ? on Server or Client ?
what OS (Server / Client) ?
which v1.9x Hotfix are you using ?

Hi Scott,

I use a variation on tdLaunchPad with the variation being that I have an 
oThread:AtStart defined to set oSession:SetDefault(.T.) as well as a few 
other options.  My application runs on the user workstation with data 
files in a shared network folder.  I currently use 2.0 but previously 
with whatever was the latest 1.9 after 2012.  My threads start with zero 
noticeable delay.  Jim's idea of AV suggests disabling AV on the 
workstation... worth a shot for enlightenment.

I use TopDown to its fullest. tdLaunchPad() and direct Thread().

There are many modules in my code which uses more than two threads and I have
not noticed any sort of delay due to thread.

Check database opening, which takes most time.
