------- Comment #9 from luisgpm at linux dot vnet dot ibm dot com 2008-09-17 15:22 -------
Gathered some PPC 32/64 performance numbers with the patch (based on 140409).
No noticeable performance regressions were found. 32-bit swin and 64-bit art
had a little boost on speed (7.8% and 3.4% respectivelly).
