懶人的Linux效能調校-tuned

--- tags: Kernel description: Linux Kernel tunning for lazzy people like me. robots: index, follow --- # 懶人的Linux效能調校-tuned :::info 1. sles 12、15的安裝方式沒什麼差異，config也可以另外依照自己所需要的狀況調整，不見得100%全部都要照預設的組態檔套用。 2. 效能調校非常吃硬體、韌體、OS調教、檔案系統、應用程式、網路，請不要追尋極限，沒有意義。 ::: ## 1. 安裝套件 ```shell! linux-aier:~ # zypper se tuned Refreshing service 'SUSE_Linux_Enterprise_Server_12_SP5_x86_64'.

Loading repository data... Reading installed packages... Resolving package dependencies... The following NEW package is going to be installed: mlocate 1 new package to install.

[openbenchmarking](https://openbenchmarking.org/) 2. 上面這個就很多了，還跑分呢。 ::: ## extra-1. 找不到組態？！ ```shell= linux-aier:/usr/lib/tuned # pwd /usr/lib/tuned linux-aier:/usr/lib/tuned # ls -al total 28 drwxr-xr-x 1 root root 354 Aug 30 22:08 . drwxr-xr-x 1 root root 16948 Aug 30 22:08 .. drwxr-xr-x 1 root root 20 Aug 30 22:08 balanced drwxr-xr-x 1 root root 20 Aug 30 22:08 desktop -rw-r--r-- 1 root root 12151 Dec 4 2019 functions drwxr-xr-x 1 root root 20 Aug 30 22:08 latency-performance drwxr-xr-x 1 root root 20 Aug 30 22:08 network-latency drwxr-xr-x 1 root root 20 Aug 30 22:08 network-throughput -rwxr-xr-x 1 root root 3719 Jul 22 2014 pmqos-static.py -rw-r--r-- 1 root root 4136 Dec 4 2019 pmqos-static.pyc drwxr-xr-x 1 root root 38 Aug 30 22:08 powersave -rw-r--r-- 1 root root 601 Oct 17 2014 recommend.conf drwxr-xr-x 1 root root 20 Aug 30 22:17 throughput-performance drwxr-xr-x 1 root root 20 Aug 30 22:08 virtual-guest drwxr-xr-x 1 root root 20 Aug 30 22:08 virtual-host ``` ## extra-2. 套用組態錯誤？！ :::info 會發生在15版，沒有正確套用的組態檔會被放在 /etc/tuned/ 中，修正之後重新profile就好囉。 :::
