who uses litespeed?

I've been reading a bit about litespeed, and I would like to get a feel for how many people use it, and what they think about it.

Thanks, Ben Lisbakken

Also, what's the most stable, best performance way to run a rails application on it?

Ruby LiteSpeed API (Ruby LSAPI) LiteSpeed RubyRunner (Run CGI in persistent interpreter like mod_perl to perl) FastCGI Mongrel CGI

Use their LSAPI as they provide support for it and the configuration is simpler.
