[clamav-users] Daily.cvd file

[Paul Kosinski]

Hi,

I'm running ClamAV 0.98.4, yet when I built it the main.cvd file was
from 17 Sep 2013 (now a year old!), and the daily.cvd files have been
about 28 MB each. Even though I have been running a local mirror on our
LAN for years now, it's really annoying that the daily.cvd files are so
big.

When ClamAV was independent, every new release had an updated
main.cvd, and the daily.cvd files were of modest size. Now the whole
0.98.x series has the same main.cvd, and the daily.cvds keep getting
bigger. The immediately previous main.cvd, in the 0.97.x series, was
shipped with 0.97.3 and was dated Oct 2011.

So now we've had the same main.cvd for a year, and before that, almost
2 years!

May I suggest that it would save everybody a lot of bandwidth if
main.cvd was updated at least with each release, and probably whenever
the daily.cvd gets so big that updating it several times a day exceeds
the bandwidth for one update of main.cvd. 

For example, on 17 Sep 2014 (yesterday), we updated daily.cvd 5 times
(checking once per hour at HH:07), for a total of about 140 MB!
Furthermore, according to Wireshark, a download was indeed about 28 MB
(no RSYNC-style compression apparently).

So, as you improve the Website and the servers, consider reducing the
total bandwidth used in some way. It will help everybody.
