I've done some benchmarking of this patch against the E850/ppc64el
Ubuntu LPAR we currently have access to and got the attached results.
pg_prewarm as recommended by Alexander was used, the tests run 300s
secs, scale 1000, each with a testrun before. The SELECT-only pgbench
was run twice each, the write tests only once.
Looks like the influence of this patch isn't that big, at least on this
machine.
We're going to reassign the resources to an AIX LPAR soon, which
doesn't give me enough time to test with Tomas' test scripts again.
