[dancer-users] Dancer on Starman, why slow down?

Hi all, Why dancer on starman becomes very slow? Am I doing something wrong? #### directly starman$ cat app.psgimy $app = sub { return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello World' ] ];};$ starman &$ ab gives me 4000 reqs/second #### directly dancer$ cat app.pl#!/usr/bin/env perluse Dancer;get '/' => sub { "Hello World!" };dance; $ perl app.pl &$ ab gives me 600 reqs/second #### dancer on starman$ starman app.pl &$ ab still gives me 600 reqs/second Why so slow?Is it possible let dancer deal with HTML request, and starman deal with non-HTML request directly?
