CONFIG_SCHEDSTATS: Collect scheduler statistics

General informations

The Linux kernel configuration item CONFIG_SCHEDSTATS has multiple definitions:

Collect scheduler statistics found in lib/Kconfig.debug

The configuration item CONFIG_SCHEDSTATS:

• prompt: Collect scheduler statistics
• type: bool
• depends on: CONFIG_DEBUG_KERNEL && CONFIG_PROC_FS
• defined in lib/Kconfig.debug
• found in Linux kernels: 2.6.10–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD

Help text

If you say Y here, additional code will be inserted into the scheduler and related routines to collect statistics about scheduler behavior and provide them in /proc/schedstat. These stats may be useful for both tuning and debugging the scheduler If you aren't debugging the scheduler or trying to tune a specific application, you can say N to avoid the very slight overhead this adds.
