Historical remark on this, the patch for MDEV-3945, This patch was inspired by the said Yoshi's blog entry - he names holding lock during THD destructor (including freeing memory) as one of contention sources, and this was easy to fix. This patch made into 5.5.29 and I think could make big difference to prior versions (70%, or something in that range, I do not recall exact number I measured)
I do have numbers :) I've just rerun the same test with MariaDB-5.5.25 (what Yoshi used) and indeed the 5.5.29 numbers are much better. XL
