in reply to Threads Vs Fork

There's a lot of guff and bluster around on this subject. And a lot of it comes from otherwise rational and reliable sources.

I needed a quick "concurrent clients" socket server for testing another piece of code against, so I knocked this up:

#! perl -slw use strict; use IO::Socket; use threads; our $ADDR ||= 'localhost:35007'; my $listener = IO::Socket::INET->new( LocalAddr => $ADDR, Listen => 5, Reuse => 1, ) or die $^E; while( my $client = $listener->accept ) { async { my($port, $iaddr) = sockaddr_in( getpeername( $client ) ); printf "From %s:%d: %s", join('.',unpack 'C4', $iaddr ), $port +, $_ while <$client>; close $client; }->detach; }

Simplistic, but it easily keeps up with 5 of these each fowarding the traffic from 100 monitored log files, so it didn't need to be any more complex.


Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
