Posted as much to check posting to list works and to raise a chuckle.
For reasons you don't want to know I have just built dbmail on a near 10
year old laptop PII 266, swear I heard the fan complaining.
To my shock on Debian 4, I'm a Linux idiot, it came up without too much
pain, mainly dependencies. (found one mistake in the install
instructions, missing ; at the end of mysql command line, which is
pretty good, works)
I then logged in across the network and hurled 16,000 emails at imap
from Thunderbird on a fast desktop.
Didn't time it but 1 to 2 a second was the rate, nearer the latter.
Is 1000 times possible?
Obviously 10x that is trivial, just about any modern machine, probably
somewhat more. Hitachi 4,200 disks are okay but for goodness sake! CPU
around 80%, no swap needed or in use. No optimisations other than kernel
has been recompiled, basically all defaults.
I suspect multiple clients would have raised the rate a little, going on
the network lights but not network bound. (100M with 32 bit card)
Split, separate DB server.
Seems a maybe.
