in thread Performance testing using Parallel::ForkManager?

Using fork (even via Parallel::ForkManager) on Windows, where fork is emulated, doesn't make much sense.

I use this for stress testing my local servers. By default it will run 20 clients, each will make 1000 (serial) connections and exchange 1000 conversations. Adapting it to your needs should be straight forward.

#! perl -slw use strict; use threads; use IO::Socket; our $W //= 20; my @t = map{ async { for( 1 .. rand 1000 ) { my $s = new IO::Socket::INET( 'localhost:12345' ) or die "Failed to connect to server: $!"; for( 1 .. rand 1000 ) { print $s "Message $_"; scalar <$s>; } close $s; } }; } 1 .. $W; $_->join for @t;

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.
