| 4 | Subject: [PATCH 109/126] init_task: faster timerslack | ||
| 5 | |||
| 6 | the default tuning is a compromise between client power and server | ||
| 7 | performance; | ||
| 8 | for a server distro like Clear Linux, we don't need to compromise. | ||
| 9 | (for non-server usages we have different kernel binaries) | ||
| 10 | |||
| 11 | in principle this can be done as a patch to systemd as well, but we have | ||
| 12 | a shared | ||
| 13 | systemd between usages while we have different kernels, so the logistics | ||
| 14 | for where the patch goes work out better here | ||
