EDIT: NOT A PROBLEM, I should use TCP_NODELAY with setsockopt. Dammit... Problem: I can't set TCP NODELAY in perl, but I can set with ruby and python. Why? I try with Perl 5.12.2 and 5.18.1!
$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
$ perl -v
This is perl 5, version 12, subversion 2 (v5.12.2) built for x86_64-linux
$ python --version
Python 2.7.5+
$ uname -a
