performance tests on php, perl and cgi

Keith Winston reports on a test he conducted comparing the three typical open source tools. I expected php to perform well because it supports some pretty high performance sites in real life. The full report is linked, but the essentials are clipped here.

That said, the results of these tests show that for many common Web programming tasks, PHP (mod_php) has a slight performance edge over Perl (mod_perl), based on the majority of the HTML generation tests. In the MySQL test, PHP also edged out Perl. I suspect the MySQL results are a reflection of the database drivers more than the interpreters.

Both mod_perl and mod_php have an enormous performance advantage over standard CGI, as expected. Standard CGI not only doesn't scale very well, but gains no advantage from concurrency. Under load, it could bring a server to its knees quickly.
