Out of curiosity, what ApacheBench options did you use?

With 10 concurrent connections performing a thousand requests each 
against HTTP.lua [1] running under tcpserver [2], I get the following:

% ../ucspi-tcp/tcpserver -o -D -H -l -R 0 1080 lua TestHTTP.lua&

% ab -n 1000 -c 10 http://localhost:1080/hello

Requests per second:    81.48 [#/sec] (mean)

Using persistent connections speed up things quite a bit as this 
doesn't require to start a new VM for each request:

% ab -n 1000 -c 10 -k http://localhost:1080/hello

Requests per second:    819.00 [#/sec] (mean)

Compiling your lua code (e.g. luac) does help a bit, specially if you 
are under a CGI type of environment.
