Hello Team,
We are leveraging ClamAV agent for our vm's malware detection.
we tried to scan a vm with 30GB used space and it took approx 1.30Hrs(we
tried to capture certain file extensions to reduce number of files and
passed file lists as arguments to clamdclient)
Note:
1. we tried above test with 4 core 8GB vm
2. We tried clamdscan as below
/bin/parallel -j 10 clamdscan -m --fdpass --no-summary --file-list
parallel is running the scanner 10 times isn't it ?
so each scan takes 9 minutes (90/10) ?
You only have 4 cores, so why do ten things at once ?
Since you use clamdscan, most of the work happens in the clamd daemon
processes. How many of those are you running ?
Does it make sense to use -m *and* parallel ? I don't know.
How long does it take to read 30GB of file from storage ?
On my (old) machine it takes 3minutes. Three times that to
scan for >8million viruses doesn't sound too bad to me.
we have below queries
1. Where can we find bench mark results for clamdscan?
2.What is the recommendation to make the scan faster for 30GB?
3. What is the recommendation if we have a VM of size >~500GB.
I really appreciate any kind of support here. It helps alot.
Thanks,
Vijay
