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
Ok, let's start from the beginning.
Have you come here with a specific problem that requires a solution
or do you just want to talk about it?

To make any useful advice, we're have to know something info about:
- Task you want to solve
- Your expectations
- Your requirements
- Your possibilities
Without this abstract questions about abstract overhead (and you must
understand it as Performance Engeneer you said) from you seems
I'm not sure why you are trying to characterize performance overhead as
"issues". Every process running on a server has some resource requirements. I
am. Performance engineer and my focus is in getting the most out of every
infrastructure server. Hence my question about overhead. In this case
If I complain about overhead/performance issue, I should:
-Specify hardware/infrastructure details
-Usage of system (some specific)
- Root case (For example "I test 4 Gb-size ISO images and I has CPU
overhead")
WIthout this it is only blah-blah-blah.
For example: In my case, I have 2 socket
So, what?
Real-life experience is useless without full
infrastructure/configuration comparison.
So, you not focused on real performance issues in this context, just
bla-bla-bla. What overhead? On what tasks? On what infrastructure/hardware?
What else I miss?

No numbers.
I'm pretty sure Larry's EULA prevents you (and me) from publishing numbers.

Hello,
For what it is worth, the two most used packages for ClamAV per the survey by
customers are Ubuntu and Debian. I have had no issue running ClamAV on RHEL or
Solaris.
I hope that in the near future, the ClamAV team will be able to focus on
performance improvements, better monitoring of
The need is not about issues, or comparisons, it's about real-life experiences
with the product and the overhead observed. Of course we'll do our own testing
but the earlier we know, the better. We also know some features will cost more
in terms of overhead than others, so I'm looking for real
What are you looking for? Performance complains? There is not.

ClamAV runs on this server and it's ok.
Built from sources.

Just get GCC 5.5 from https://opencsw.org
OpenCSW is free and easy to use on Solaris.

Any relative numbers you can share?
Thanks very much, Len Sanschargrin

Unixpackages is paid service and I don't think it is good.
On Solaris better to build ClamAV from sources. This is trivial.
It's works perfectly last four years on my Solaris servers.

It plays on RHEL and Solaris a lot better than Symantec.
You should get your Solaris builds from www.unixpackages.com.

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
US-CERT alerts often contain a "consolidated rule set for malware associated
with" the relevant activity. See e.g.:
https://www.us-cert.gov/ncas/alerts/TA18-074A
Yara rules are listed, so that they can be copied and pasted into a file to be
saved in /var/lib/clamav in order for clamscan to use

I know nothing about YARA but you could try escaping the hash in case it
is being treated as a comment line.
e.g \#a > 1
The comment metasymbol for Yara rules is "//", but I tried this anyway
as a long shot:
$ clamscan -d foo.yar
LibClamAV Error: yyerror():
I believe the developers are hard at work planning for the future this week, so
they can probably can give you better answers than I later on.
I suspect some of this may be platform specific, so my answers are based on my
macOS experience.
clamd scans every file that clamdscan tells it to, so
18 matches
