Hi,
 thanks for the patch.
 When you include a patch as an attachment, I find it easier to work with if
 it is "text/plain" rather than "application/octet-stream".

 As your patch is justified as a performance improvement, please include
 some measurements together with a rough description of the hardware (one or
 two sentences).

 Also, the performance improvement requires that multi-threading is enabled,
 which isn't the default.  Please measure the effect of the patch when
 multi-threading not enabled.
 Maybe we should make the change you suggest be conditional on threading
 being enabled, but we can't know without numbers.

Thanks,
NeilBrown
