Hello, I have customer who is preparing to implement ClamAV on RHEL and
Solaris. As the Performance engineer, I'm looking for any testing or stats
on potential overhead can be associated with running ClamAV. Even just
anecdotal observations can help us to set expectations and of course any
addition

Our hosts have asked us to be civil and friendly in our discussions here. If
you can't uphold such principles, then perhaps you should look elsewhere for
answer.
As has already been stated, you really haven't given us much to go on. There
are lots of configuration options and hardware factors t

Thanks very much, Len

Firstly, as other
I ran it on dozens of enterprise systems, real and virtual, under RHEL and
Oracle Linux. As a mail scanner running on demand it was never a great issue
regarding performance as they were dedicated servers. But we found that when
scanning file systems for compliance it would thrash the disk cache

1. With regard to separating signature sets:
Isn't there always a danger that scanning with a reduced signature set
misses malware that was not "expected" in a particular context? For
example, except in highly restrictive work environments, people tend to
visit all sorts of Web sites, any of which
Yes to all of those concerns, Paul.
As far as the reduced signature sets, it’s possible to run multiple instances
on the same box in order to speed each individual reload. For example, you
could have one instance that only loads the ClamAV databases and only reloads a
couple of times a day and
