At InnoCraft we are running Piwik for large and very large websites and have identified challenges in memory usage during pre-processing of report data.

The goal of this ticket is to investigate with XHProf profiler, and find the cause of these memory issues and fix them.

Archiving memory required before investigation started: 8Gb.

Memory after the ticket is implemented: 1Gb.

THE POWER OF BETTER CODE. NO LEAK.
