Probably this is due to the fact that I didn't apply yet the first patch of the series (the one that increases the batch to 32), so I guess I'll defer this patch until we can apply the rest of the series. Also, if you guys see an improvement (and since you got some evidence with VTune), I don't think it matters that on one particular system (mine) I can't see any benefit.
