What are the differences among

LiteSpeed Web Server V2.0.7 Standard Edition

and

[BETA] LiteSpeed Web Server V2.1RC1 Standard Edition

?

Main differences are: LSAPI, PHP LiteSpeed LSAPI and a stateless load balancer.

More information about LSAPI: http://www.litespeedtech.com/lsapi/

and another question :)

Is this normal:
nobody 26542 0.1 0.6 7920 5576 ? S 11:01 0:01 admin_php
nobody 26543 0.0 0.1 4704 1652 ? S 11:01 0:00 admin_php
?
I mean - each time i see not less than 2 instances of fastcgi script,
this behavior not depends on the type of fastcgi script and number of instances in configuration.

It is normal, admin_php is the internally defined PHP FCGI External App for the web admin interface, whenever web admin interface is accessed, you will see those processes, your configuration has no effect on those.

hm, I understand that. admin_php is just an example,
the problem is:
I have more than 2 instanses for EACH fastcgi script, my script:

nobody 26572 0.0 0.1 2496 1152 ? S 11:01 0:00 /bin/sh /home/bos.cgi
nobody 26573 0.0 0.1 2496 1152 ? S 11:01 0:00 /bin/sh /home/bos.cgi

and I never seen only one instance of /home/bos.cgi

For various reason, LSWS always try to start additional FCGI process when "instances" > "1".
If you set both "max connections" and "instances" to "1", then only one instance will be started.
