log the size of scanned stream and elapse time

[ralfhauser]

Describe the feature request

We would like to analyze timing issues with streamed scans.
We set in /etc/clamav/clamd.conf

LogClean yes

Unfortunately, in the log we do not see the size of the stream nor the elapse time.

Especially if the LogVerbose true is set.

In /var/log/clamav/clamav.log currently we only see

Interesting was that the same 17mb pdf takes approx 50 secs. and during a second try, only approx <=4 secs

The second scan would be fast because clamd keeps a relatively small cache of clean files. You can disable the cache with the clamd.conf option:
DisableCache yes

You can increase the size of the cache with: CacheSize <some custom value in bytes>
