Quixote and Lighttpd
Lighttpd is a another Web Server with very promising features: Security, speed, compliance, and flexibility.
As of version 1.3.14 scgi is supported ;-).
Where to download and how to install?
Please refer to the Lighttpd web site: http://www.lighttpd.net/download/
Specific configuration modifications will be explained here after.
SCGI performance: Lighttpd vs Apache
Equipment
- AMD Athlon XP2000+ (1659 MHz)
- 256 MB Ram
- Linux 2.4.26
Apache Bench
Version 2.0.41-dev <$Revision: 1.121.2.12 $>
lighttpd
- version 1.3.15
- installed via: "emerge lighttpd-1.3.15-m1"
- Indeed, I've changed the ebuild script to have the -with-lua and with-memcache. But this would not impact our scgi tests.
- added in /etc/lighttpd:
scgi.server = ( "/scgi-test" => ( "localhost" => ( "host" => "127.0.0.1", "port" => 3000, # "socket" => "/tmp/scgi.socket", "check-local" => "disable" ) ) )![/!\](./modern/img/alert.png "/!\")
You must comment (host + port) or (socket). 
in gentoo all programs linked to apache-2.x have a 2 at the end. Thus we have ab2, apxs2, apache2, ...
apache
- version 2.0.54-r5
- install via "emerge apache2"
- with scgi enbabled (/etc/conf.d/apache2): APACHE2_OPTS="-D SCGI "
- apache config is like this:
<Location "/scgi-test"> SetHandler scgi-handler SCGIServer localhost:3000 SCGIHandler On SCGIServerTimeout 10 Options -Multiviews </Location>
scgi
- version 1.4
- install manually:
tar -xzvd ... cd scgi-1.4 python setup.py install cd apache2 apxs2 -i -c mod_scgi.c : scgi developers have forgoten to update "version" string. You still will see 1.2 displayed. Thus if you upgrade, takes care.
Quixote 2.0
- Install via standard "tar -xzvf ...; python setup.py install"
Benchmark
I will use the 2 following tests (with root user):
nice -n 20 ab2 -n1000 -c5 http:/localhost/...
nice -n 20 ab2 -n1000 -c50 http:/localhost/...
scripts used:
To be able to test socketfile, I'm using an updated version of scgi_server.py.
The script used can be downloaded: runscgi.py.
Because I will not specify any factory, this one will be used: quixote.demo.create_publisher
Results summary
I will run each commands 3x, and I will present the results of the third run.

Conclusions
With a normal sockect connection, Lighttpd is +- 25% quicker than Apache.
With Unix Socket file, Lighttpd is +- 30% quicker than Apache (still with normal socket)
