Hello,

Well I'll say that it's hyperbole to be on the safe side, but you might want to
look at this:

Some people say that it's a Rails problem but why has Ruby the place it has
on the shootout?  Can't they indulge in some malloc+pointer-arithmetic tricks
like our Haskell brothers :) ?

Well these are pretty good numbers IMHO.  My own monadically threaded homegrown
"framework" tops at about 300 reqs/seq at ronchonneuse.com (native code,
a Dedibox on a VIA Esther at 2GHz), and it goes thru Lighttpd via SCGI
(FastCGI should improve it but it's not worth the hassle for now.)

Could be, but not in bytecode.  Let's place our hopes in natdynlink!
