And how many workers does apache have? I think thats what you're seeing

This is what I tried, can't get simpler/faster than this, cgi-bin/printenv.pl

#!perl
print "Content-type: text/plain; charset=iso-8859-1\n\n";
foreach my $var (sort(keys(%ENV))) {
    my $val = $ENV{$var};
    $val =~ s|\n|\\n|g;
    $val =~ s|"|\\"|g;
    print "${var}=\"${val}\"\n";
}

This one does more (loads modules) so it should be slower , dumpenv.psgi started with plackup -l 127.6.6.6:80 dumpenv.psgi 2>2 1>1

#!/usr/bin/perl --
use CGI();
use Data::Dump qw/ dd pp /;
my $app = sub {
#~     die "@_";
    my $q = CGI->new( $_[0] );
    return [
        '200',
        [ 'Content-Type' => 'text/html',
          'Content-Length' => '2',
        ],
        [ $q->start_html, $q->Dump, $q->end_html, ],
    ];
};

Then see whats faster


for ( 1 .. 10 ) {
    cmpthese(
        1000,
        {
            'psgi' => q{
#    LWP::Simple::get('http://127.0.0.1:5000/');
    LWP::Simple::get('http://127.6.6.6:80/');
    qw//;
                       },
            'apache2cgi' => q{
    LWP::Simple::get('http://localhost/cgi-bin/printenv.pl');
    qw//;
                             },
        }
    );
}

I tried it a bunch of times, and psgi is faster "half" the time (ok 4/10 or 3/10)

My Apache is configured with ThreadsPerChild 4 -- not sure how many actual workers that is on my machine, but I see two apache processes ... one has 1 thread the other has 6, so 6 or 7 workers?

But yeah maybe the LWP is skewing the benchmark or .... something I dont understand
