We used to use this perl module in production about 3 years ago for
relatively heavy production traffic (we have way more traffic today)
but it was slow, unscalable, and blocking on I/O. We switched to the
ngx_http_lua_module since then and it has been much faster and
guarantees 100% nonblocking network I/O. Disclaimer: I am the
maintainer of the ngx_http_lua_module.

See https://github.com/openresty/lua-nginx-module#readme

We still use Perl for many offline work like automated testing (based
on the CPAN module Test::Nginx [1]) and WAF's Lua code generation (the
modsecurity rules to Lua translator is written in Perl). I've also
been working on the Lemplate compiler [2] in Perl that compiles Perl's
TT2 templates down to standalone Lua code runnable atop the
ngx_http_lua_module.

Hope it helps.
