We've been tryin to do some more reliable and dependable benchmarking of
qmail in our experimentation, but it is very difficult. One of the "nice
things" (one of?) about ms smtp server is the fact that nt performance
monitor can keep track of it. We can see how many messages per second are
being sent, how many concurrent connections, etc. While it is easy to
monitor concurrent connections by a good old ps auxww |grep qmail-remote
|wc -l, it is not exactly well represented, nor scientific. Messages per
second can really only be done by monitoring qstat and a stop watch, or by
sending to a pool of ms smtp servers and monitoring them. It would be truly
wonderful if we could get more concrete and scientific results of all of
this, because I think it would be an excellent way to demonstrate the power
of qmail, and I think it would be a wonderful tribute to everyone who has
put their time into the project. They all deserve a lot of credit, and this
seems to be the best way to give them that due credit. Are there any
available benchmarking tools? If not, I think it would be worthwhile to
develop them. If no one is interested in developing them, we may be able to
devote some internal time to doing it, provided we can get some insight into
the inner workins of qmail, etc.
