Ugh, that's assuming your fixes for the "perf" mode are in, which I
thought wasn't the case yet ... without them, "perf" does very wrong

Right, the output he provided has the MRRS clearly changing in addition
to the MPS.

Ideally, we'd need the output with current upstream vs. with before your
very first patch went in and compare that.

Also, Avi, can you send these outputs like patches ? IE without wrapping
them ? That would be handy :-)
