Bug ID: 29296
Summary: tpcc-mysql scores decreased by about 11.2% at
glibc-2.36
Product: glibc
Version: 2.36
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: yangyanchao6 at huawei dot com
Target Milestone: ---
At Kunpeng920 platform, tpcc-mysql scores decreased by about 11.2% between
glibc-2.36 and glibc2.28 with mysql-8.0.20.
Comparing the code, I find that the two commits causes performance degradation.
11a02b035b46 (misc: Add __get_nprocs_sched)
97ba273b5057 (linux: __get_nprocs_sched: do not feed CPU_COUNT_S with
garbage [BZ #28850])
These two patches modify the default behavior.
Another message is that my machine is 96 cores and I have 91 core bindings for
tpcc-mysql.
This means that perhaps the current approach to computing arenas is not optimal
in the case of core binding.
