An Overview of the Boa Web Server
Gentu writes "There is a pretty new and little known, lite web server in town, named Boa. The server can run very fast on older machines, even on embedded devices, but it is only CGI-based. OSNews introduces Boa (running under Linux) and it includes some preliminary benchmarks against Apache and thttpd."
It seems a little odd to compare BOA and Apache. Granted Apache is the web server of choice so a comparison is not too bizarre but, it is still an apples to oranges comparison.
Boa is much smaller than Apache. This seems like a good thing on the surface, especially for embedded applications, as was suggested in the article. But, Boa is slower and much less functional than Apache. They really aren't comparable servers.
Hi
According to my tests BOA beats Apache.
BUT the ZEUS web server (www.zeus.com) which is 'feature complete' (including mod_perl in version 4.2) still beats both of them.
Have a nice day!
I've used Boa in a number of cases where certain groups of CGI scripts need to run as a specific UID and I didn't want to use the SUID functionality of Apache. Because it is so lightweight, having a few of these hanging around for various citical system UIDs can really be handy, esp. if you have an aversion to using SUID wrappers and such. A good example is using Boa running as the same UID as the mailing list processor so you can have web administration of the list rosters. And the users don't even know about it because I use the ProxyPass directive to shuttle the requests from the standard port 80 up to the port on which Boa is running, so my logging is still centralized/standardized through Apache.
Boa is very cool. Kudos to the developers!
These are very, very different approaches to creating a scalable server.
See Non-blocking I/O is good for more background on what multiplexing is and why it is good.
MORTAR COMBAT!
