It wouldn't hurt. But you wouldn't see much of a difference,

it's probably not compiled at all. So you're not getting any
benefit from a JIT compiler.
While at this conjuncture the JIT itself doesn't make much of a difference for a typical Web app, the VM does:
% lua -v Nanoki.lua . 0 1080
Requests per second: 773.17 [#/sec] (mean)
% luajit -v Nanoki.lua . 0 1080
Requests per second: 1174.19 [#/sec] (mean)
% luajit -v -joff Nanoki.lua . 0 1080
Requests per second: 1167.37 [#/sec] (mean)

Also, if the "CGI" type launcher supports persistent connections by reusing a process for the lifetime of a connection, then one might benefit from the JIT itself at some point.
