Description Mihaela Velimiroviciu (:mihaelav) 2011-09-22 05:43:33 PDT
Memory increases appear on Linux and Windows between Sept 19 and Sept 20:
- Windows: the difference is about 17 MB, from 69 MB to 86 MB
- Linux: the difference is about 28 MB, from 86 to 114 MB

On Linux, the previous values were about 88MB (or less) constantly.
On windows, the previous values were around 75 MB (but not that constant).

This should have been fixed by bug 688292, which fixed a memory usage spike in chrome-intensive workloads where jitcode was not getting released fast enough (a pseudo-leak).  Graphs 9/24 and later look similar to the 9/19 ones, e.g. Windows:
Comment 3 Dave Hunt (:davehunt) 2011-09-27 13:07:01 PDT
Confirmed memory usage has dropped back to pre-regression values from build 20110923030857.
