Hi all,
Please find below the results from a complete GUPB run on a patched CPython
3.6. In average, an improvement of about 2.1% can be observed.
I'm also attaching an implementation of the patch for CPython 2.7 and its
benchmark results. On GUPB the average performance boost is 1.5%.
In addition we are also seeing a 2.1% increase in throughput rate from our
OpenStack Swift setup as measured by ssbench.
Compared to my proposition in issue #26382, this patch yields slightly better
results for CPython 3.6, gaining an average of +0.36% on GUPB,
and similar results for CPython 2.7.
Hardware and OS configuration:
==============================
