I haven't yet found any proper benchmarks compared to nginx, but I might try it out over this week. I wondered if anybody else has had a try and can provide some thoughts?

I just heard of this today from TAZ. This really sounds promising, and I might try it out within the week, although I wonder which features were removed.

EDIT
Hosting control panel compatibility, mod_security compatibility, .htaccess file compatibility, and page caching will remain commercial-only.

If if they just included htaccess compatability, imho this would be THE web server of choosing for pretty much everybody.

Having said that, if the issue is just adding the htaccess directives to the web-gui.... then... hmm definately onto a winner?

It still supports Apache rewrites via the Admin page (that's what I've heard, not sure), just not through .htaccess. I do the same for rewrites with NginX (having to manually open up configs) so I guess there wouldn't be a difference between the ease of use between the two. As for performance, LiteSpeed and NginX were two web servers that exceeded expectations, only NginX being better at serving static content IMO.

Dunno, but I can start this server.
Code:
[ERROR] Failed to start litespeed!
Debian 7 fresh install VirtualBox.

-edit-
I got it. Installation required curl to download PHP 5.3.24 from us.php.net and I dont have any curl installed.

So:
Code:
apt-get install curl
will fix that.

I guess they should tell us about this. :D

Okay, so I recommend to all who want to test it.

Install PHP before install Open LiteSpeed.

My bad. I mean:

Install curl and beware about your PHP version.

Looks pretty speedy to me. Hard to tell if that's the webserver or the hardware though. Will be adding a new droplet tomorrow to try it out a bit for my self.
Obviously it will be fast due to it being a new install, no data no load etc.

However, in real time I spent maybe an hour from a barebones box, installing centos + deps and then getting it running.

I've never realy used litespeed before, however, seems simple enough, so will have a better play tomorow.
