@nrk hey Danielle, 1 & 2 were just me wanting to see higher numbers, I can do the math in my head already, and this platform would smoke on a 6 core @3.2Ghz :)
I asked Ignacio of LuaNode about 3 months ago about redis integration and he said: no time right now.
So the non-blocking Lua-webserver w/ nonblocking redis backend remains to-be-done (redis2-nginx-module has done it, but I remember you wanted it done differently than they did it).
Anyways, I am polluting this gist, I have an idea about serving Lua real quick that I will offline email you about.

@nrk Any news about that Mongrel configs? :-)

@JakSprats: hehe, too bad I didn't have the time to test thoroughly that beast when it still was without the hypervisor installed (it's a dual Xeon X5660, 2 x 6 cores @ 2.8 GHz). PS: just got your mail, will reply tomorrow.

@agladysh: as soon as I can get that VM up and running again (I don't have access to our VPN right now) and review my hackish installation, I've been busy today but I guess I can get it done over the weekend.

@nrk: OK, thanks, no hurry here :-)
