Hi dear developers!
Does somebody like explain me the architecture of the JabberD server?
Some talks made me curious.
Is it based on Select() API call?
Or is it multithreaded with NewPosixThreadLibrary layer?
Is it a hybrid architecture as Apache with main nodes as processes (fork)
and childs as threads?
Which BSD sockets mode it use? Async? Sync?
It use Expat XML lib?
Does it use some pattern?
Just to share some thoughts, as curiosity.
Thank you :)
Roberto

Hi,
Sorry for the delays,
I don't like publish too much characteristics for now,
You have to know that the system has 4GB RAM, and every socket use 1KB of
phisical kernel RAM, then a "cache" in kernel for shared writes.
The system use a proprietary XML XMPP parser, part of a ultra performing
RuntimeTypeLibrary that I have named DreamRTL.
The test was into a big lan, and I'm in touch with italian university to
bring a certification.
Thanks for your interest.
Roberto :)

Cool! How did you test it?
Simulated 600K jabber clients with protocol incl. login, presence, messages,
etc.?
