Investigate setting init_on_alloc=0 on cache hosts
Open, LowPublic

Description

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6471384af2a6530696fc0203bafe4de41a23c9ef

Debian has init_on_alloc=1 by default. It may be worth setting it to 0 in the kernel command line to compare performance. redis-benchmark for example shows a ~8% performance improvement with init_on_alloc=0

Event Timeline

This is worth investigating/researching but I am marking this as "Low" and we can revisit it for Q3 2025-2026.
