The precompiled version seems to have been compiled under a 2.4.x kernel that uses the badly implemented LinuxThreads library, which is nothing more than a stripped down forking to simulate threads and, thus, each thread appears as a separate process with its own PID.
Atif's version is most likely compiled under a 2.6.x kernel (a more recent Linux distro), which uses the newer Pthreads libraries that implement true-threading, which do not appear as separate processes. Real threads share the same PID as the parent process and performance is several orders of magnitude superior to the old implementation.

Is there any differences between the way that you are bringing these two programs up? For example, you are running the precompiled one manually, while the one that you compiled yourself is defined as a system service. -Bahram. ----- Original Message ----- From: Atif Rasheed To: openh323gk-users@xxxxx Sent: Monday, October 10, 2005 6:09 AM Subject: gnugk multiple threads..../configure options Hi all, I am using gnugk 2.2.3-2. now I can see a difference in my own custom compiled gnugk and pre-compiled gnugk available online at http://www.gnugk.org. I have compiled gnugk with these options ./configure --disable-mysql --disable-pgsql --disable-radius --with-large-fdset=4096. and I have set RtpHandlerNumber=10 and CallSignalHandlerNumber=10 now when I execute these two gnugk's seperately. I can see ( from 'ps aux' )the precompiled version running with multiple threads where as I can't see threads in my own custom compiled version Is there any ./configure option I am missing, Please comment !!!
