1) Yes, it is slow.
2) Yes, it wasn't always like this (and hence you could down-grade to an older
version if you needed).
3) Newer versions are faster (see below).
4) Yes, it still can be used for a mail server (I know, as I'm still
using it).
> Mandriva 2007.0 on a 800MHZ Duron, 512MB RAM
Pretty wimpy mail server by today's standards (due to spam/virus counts).
I've not run on a machine like that for years (though that was a nice machine
for a mail server just 5-6 years ago).
> rpm -qa |grep clam
> clamav-db-0.90.2-0.1mdv2007.0
> libclamav2-0.90.2-0.1mdv2007.0
> clamav-0.90.2-0.1mdv2007.0
Upgrading to 0.90.3 will probably speed things. When I went from 0.90.2
to 0.90.3 my average mail processing time went from 4 minutes to 2 minutes.
Upgrading the the latest RC code will probably make it very fast (seconds
instead of minutes) though you have to decide if you can or can not run
RC code.
And of course, you can do other things like run clamdscan+clamd instead,
or put your clamav databases on a RAMDISK to try to speed it up some, etc.
But I am always waiting for either the RC code to get released, or for
someone reliable to release the RC code as an RPM for my OS versions.
It is annoyingly slow, though still usable, as is.
