No it's not clear to me?? How does it checking every 60 min for 2 seconds slow down your server?
Well, it is a question of big numbers
.
Currently we have well over million users of avast! HE. And usually about 1/3 of them do update during the default four hours period when the iAVS update is released. It means that every second about 30 users are served. If we change this period to one hour, it will be about 120 users per second which is quite close to DDoS (Distributed Denial of Service) attack to our servers.
Of course we do not rely on one server but our servers are not used for the iAVS updates only - for example we have more than 12000 program downloads from
CNET only during last two days (which represents about 84 GB of transferred data). So it is a question of data distribution.
Of course if only you change it, it makes no difference. I believe that even if all forum users (> 2600 people) change this parameter, the influence will be close to nil. But it is the principle question - we think that the four hours period is optimal for both of you and our servers, otherwise we could face the situation that our servers will not be able to deliver the updates and no users will be able to update...
