Von wegen schlechte Datenstrukturen.
Hier mein getestetes Script:
Code: (dl )

#!/usr/bin/perl
print "Content-Type: text/html\n\n";
print "hallo";


Hier sind die Benchmarks mit folgender Einbindung in der httpd.conf:
Code: (dl )
1

<FilesMatch "hallo\.pl$">
    SetHandler perl-script
    PerlHandler ModPerl::Registry
    Options +ExecCGI
</FilesMatch>

Meine Frage: warum ist das einfachste script der Welt MIT modperl fast doppelt so langsam wie ohne modperl?
Welchen Sinn erfüllt denn dann modperl überhaupt?

Ich habe folgendes Bench genutzt:
ab2 -n 100 -c 5 http://localhost/cgi-bin/script.pl\n\n
