I running piwik at my site http://www.towerdefensehq.de/
There are above 3.000 Visitors a day. Tracking is fine and seem to have data of the same quality as Google Analytics which I used before.
But the amount of collected data bugs me a bit. TDHGQ collects steadily 1MB each day. 30 Days equals 30 MB.
I fear if I would add all of our customers to the piwik database I would collect a too large amount of data.
Is this normal? Can this amount be reduced? More sites will hash more data and the database will be smaller or something?
