Voodoo chat 1.0

Voc is a stream-chat engine which is designed to work on high-loaded chat-servers.
Voc is a stream-chat engine which is designed to work on high-loaded chat-servers. It is written in PHP, but uses Perl or C++ for Voc-daemon -- the special program to handle multiple user-connections. With Voc you can make a chat that will serve many conversations simultanously. And it's html-based, so your chatters can use it from almost any browser.
The Voc-engine includes a lot of features so it will be interested not only for a big chat owners.

What's so special about Voc-engine?
There are 2 classes of html-chats. Classic-type, with refreshing messages-window, And stream-type.
Refresh-type is known to everybody, so let's think about streams. What is the common way to introduce such functionality? Webmasters make cgi-script (PHP-script, jsp-srcpt, e.t.c) which checks for new messages every second (2,3...) and prints something to the client. Of course, you need one instance of the script for each client. Now calculate how many data-requests you need to process every second... At least two for each client -- get messages, get users-list.

Also don't forget about memory and CPU usage. For instance, if you have PHP-scripts and PHP is compiled as an Apache-module, be ready to spend 5 Mbytes of memory and 0.1-1% of CPU for each client (only for messages-window).Multiple it to number of users online.
Do you still want to use such scripts?

Is there any solutions? I guess, yes -- try Voodoo chat. It uses Perl- or C++-daemon which processes users-requests to a messages list. And you need just one daemon for all clients. This daemon takes approx. 10 Mbytes of memory for 100 users. CPU usage is also small (of course it depends on your CPU, i.e. for 100 users online it is 0.5% of Pentium 4 2.4 Ghz). Do you see the difference now?
