Hi,

I would like to thank everybody who gave me some advice while trying to
solve my performance issue.

After introducing clamd and starting the scanning for attachements with
clamdscan performance increased. Scanning an attachement larger than 4
megabyte now takes seconds rather than hours. I only hope the clamd daemon
is stable.

Regards,

Jan

Subject: [Clamav-users] Clamscan slow on large attachements


All,

I was strugling with clamav this weekend for a few hours without any
success. So, I decided to ask it on this mailing list. Hopefully someone
can give me a hand and point me in the correct direction...

Clamav is running from qmail-scanner on my site and is working quite well.
The only thing  I have, is when a user sends an email with a large
attachement (>4Mb) from Outlook Express for example. The mailserver
happilly accepts this email and starts checking if the attachement
contains a virus. While the server does this, it keeps the smtp session
open. The problem is now that attachements >4Mb are taking ages to scan.
The CPU is now busy for 100% running clamscan.

Because the users connect with Outlook Express this application will now
say to the user that the mailserver is not responding (since the smtp
session is still open) and asks the user what to do, wait or stop ?

With this in mind I have the following questions:

1) Can I configure clamscan so it will operate faster ?
2) Can I configure qmail-scanner to disconnect the smtp session and starts
clamav in the background (probably a qmail-scanner question) ?
3) Does anyone have experience with such a setup ?

Thanks in advance !

Regards,

Jan
