V2EX-服务器内核的 PSI 指标保持在多少以下比较合适？

everyx:

大家对内核的 PSI 指标有了解么？一般在服务器上多少比较合适呢？如果超过了是不是得提高配置？

以下是我 do 2c4g vps 的数据

root@do02:~# head /proc/pressure/*
==> /proc/pressure/cpu <==
some avg10=21.84 avg60=27.12 avg300=25.19 total=30134617854

==> /proc/pressure/io <==
some avg10=0.14 avg60=0.26 avg300=0.26 total=468701460
full avg10=0.10 avg60=0.11 avg300=0.10 total=303083399

==> /proc/pressure/memory <==
some avg10=11.42 avg60=14.50 avg300=12.44 total=14450836353
full avg10=0.00 avg60=0.00 avg300=0.00 total=84280946

谢谢大家
