My results on Windows 2000: OK for 20000 threads - 20 threads running in parallel 1000
Results on Linux (Red Hat 7.3): OK for 20000 threads - 20 threads running in parallel 1000 Interestingly, on Windows (in a DOS window) if the window has focus, it runs very slowly. Bring another window forward, and the thread test runs at almost Linux-speed ;-) Cheers! -- David Hancock | [EMAIL PROTECTED] | 410-266-4384 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of James R.

I have been experiencing times when my Webware site at http://zunzun.com will simply stop running, cause unknown. Investigation to date shows that there is some thread problem, which I would like to discuss. Below is a simple Python program to test multithreading. This program runs smoothly and quickly on my home Windows XP computer as expected. On the Linux server where my site resides, it runs slowly and jerkily, finally ending with the message "Killed". I would like to ask that others please try this program and see how it runs on their computers, this may be why people occasionally report unexplainable WebKit site applications stopping. If there is a problem with my test code, please let me know. I do not see one and don't know why it runs differently on the two computers I have access to.
