That's quite interesting. Where was this, if you don't mind sharing
The spamassasin example was at Sify. At that point we were hit by spam and
virus
specifically targeted at Sify. And the servers were just not able to cope up
with the load. One night of frantic coding and the spamassasin was replaced
by bogofilter. A program called qmail-smtpd was modified to look at the exit
code of bogofilter and discard the mail at the entry points.
bogofilter is a very fast bayesian spam filter available at
http://www.bogofilter.org
Currently we are doing some of this stuff at my current job. Just few days
back we have got a huge performance gain by moving to sphinx -
http://www.sphinxsearch.com/ ;(written in C++) and we are
again going to save on servers by moving away from Lucene -
http://lucene.apache.org/java/docs/ ;(written in Java)
that. I haven't written much C at work, and I guess I've never seen
much industrial C either then. Never would have expected to be
hovering right near assembly.
Take a look at
http://highscalability.com/
It explains the architecture of high scalable sites like youtube, flickr,
etc. I have personally gained a lot from the above site.
