[OS-BUILD PATCH] redhat: configs: decrease CONFIG_PCP_BATCH_SCALE_MAX
by Rafael Aquini (via Email Bridge) 15 Oct '24

15 Oct '24

From: Rafael Aquini <raquini(a)redhat.com> redhat: configs: decrease CONFIG_PCP_BATCH_SCALE_MAX In page allocator, PCP (Per-CPU pageset) is refilled and drained in batches. The batch number is scaled automatically to improve page allocation/free throughput. But a too large scale factor may end up hurting latency, like observed on https://issues.redhat.com/browse/RHEL-59526. We're bringing this down to 0 for RHEL, to provide a smooth linear scaling factor as opposed to the default exponential scaling factor.
