207 Install zlib, how can not AH

Because Piwik's click has a number of SQL queries, one will be more than 1000, one will go down again, but again because it is Piwik source code, codes do not understand, so at the level of code is no good way.

I have always suspected that the database is too large because a common database table has reached 14G. So I use Piwik backstage function, deleted some data, in addition, there is a large number of visits today, click Load is high, there are reasons for this, to the afternoon, the end of the activity, so the traffic is not so high, so it is better. So, it is not certain that the reason for the deletion of data, or the cause of the decline in activity, wait until tomorrow.
