I tried to relax the upgrades, but I see the problem is the time spent
to reload the db:
2015-09-29T01:03:15.710526+02:00 av2 clamd: Reading databases
2015-09-29T01:03:53.151179+02:00 av2 clamd: Database correctly
reloaded (5342845 signatures)
Is there a way to speed up this phase? Maybe putting the db files into
a RAM fs?
Thank you very much
