I ran another scale=5 TPCH benchmark on v4 against f859c2ffa using gcc
9.3. I'm unable to see any gains with this, however, the results were
pretty noisy. I only ran pgbench for 60 seconds per query. I'll likely
need to run that a bit longer. I'll do that tonight.
I've attached the results of a TPCH scale=5 run master (f859c2ffa) vs
master + elog_ereport_attribute_cold_v4.patch
It does not look great. The patched version seems to have done about
1.17% less work than master did.
I've marked this patch back as waiting for review. It would be good if
someone could run some tests on some intel hardware and see if they
can see any speedup.
What is the way forward here? What exactly would you like to have tested?
