Rob Godfrey commented on QPIDJMS-402:
-------------------------------------
[~gemmellr] so I've now tried two more Mac laptops. On my 2017 15" MacBook Pro
I saw 0.34 being faster than 0.33 (though nowhere near as dramatically as the
improvement I saw on Fedora). On my 2013 13" MacBook Pro I see numbers much
closer to those from my 2018 12" MacBook (non-Pro) which I shared earlier.
Unlike the first laptop, the 2013 13" has active cooling and so is not
thermally throttled in "normal" operation, yet I get 11500msg/s on 0.33 and
8800msg/s on 0.34 ... so I think the best we can say is that results on OS X
are hardware dependant (all the laptops are running OS X 10.13).
