前言
近期在PVE中發(fā)現(xiàn)，只要連接數(shù)一多，PVE會(huì)有兩個(gè)單核的使用率明顯比其他核超過一大截。經(jīng)過查詢資料發(fā)現(xiàn)，這是因?yàn)槲业?RealTEK RTL8125 2.5GB 網(wǎng)卡默認(rèn)加載的驅(qū)動(dòng)是r8169，它并沒有開啟網(wǎng)卡多隊(duì)列等特性。導(dǎo)致一個(gè)網(wǎng)卡的軟中斷只能使用固定的一個(gè)核心開接收和發(fā)送數(shù)據(jù)。
查看網(wǎng)卡加載的是什么驅(qū)動(dòng)：
## 看看網(wǎng)卡的pci編號(hào)
$ lspci | grep RTL8125

2a:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
## 看看網(wǎng)卡加載的驅(qū)動(dòng)
$ lspci -s 22:00.0 -k # 22:00.0這塊網(wǎng)卡

查看網(wǎng)卡軟中斷數(shù)量：
$ cat /proc/interrupts | grep -P 'eth|CPU0' # 我的網(wǎng)卡名叫eth0、eth1
CPU0 CPU1 CPU2 CPU3 CPU4 CPU5 CPU6 CPU7 CPU8 CPU9 CPU10 CPU11 CPU12 CPU13 CPU14 CPU15

也可以用這個(gè)命令看看軟件中斷（%soft）是不是大量集中在某個(gè)核心上。
$ mpstat -P ALL 1 5
連接數(shù)多的時(shí)候，甚至這兩個(gè)核心的使用率能達(dá)到80%，而其他核心才不到20%。所以還是有必要將該網(wǎng)卡驅(qū)動(dòng)從Linux默認(rèn)的r8169切換到官方驅(qū)動(dòng)上。
使用官方驅(qū)動(dòng)
已經(jīng)有大佬把官方驅(qū)動(dòng)打包成了dkms deb包：realtek-r8125-dkms，不過該deb包并沒有打開網(wǎng)卡多隊(duì)列，所以我FORK了一份，啟用TX多隊(duì)列及RSS，禁用ASPM，發(fā)布在：https://github.com/devome/r8125-dkms ，直接使用即可。先下載Release中最新的deb文件，再按下方流程安裝即可：
## 更新內(nèi)核、安裝依賴
$ apt update
$ apt upgrade
$ apt install -y dkms pve-headers #pve 8.0.4+建議將pve-headers替換為proxmox-default-headers
## 安裝headers
$ headers=$(dpkg -l | awk '/^ii.+kernel-[0-9]+\.[0-9]+\.[0-9]/{gsub(/-signed/, ""); gsub(/kernel/, "headers"); print $2}' | tr "\n" " ")
$ eval apt install -y $headers
## 安裝剛剛下載好的deb包，此命令只會(huì)為當(dāng)前系統(tǒng)所使用的內(nèi)核以及剛剛安裝的最新內(nèi)核（也可能當(dāng)前所使用的內(nèi)核就是最新內(nèi)核）安裝驅(qū)動(dòng)
$ dpkg -i r8125-dkms_*.deb # 如通配符會(huì)匹配多個(gè)時(shí)亦可指定具體的文件名
## 如果想為那些既不是系統(tǒng)當(dāng)前所使用的內(nèi)核，也不是剛剛安裝的最新內(nèi)核安裝驅(qū)動(dòng)，需要手動(dòng)指定安裝
## 看看哪些內(nèi)核安裝好了驅(qū)動(dòng)
$ dkms status
## 列出全部?jī)?nèi)核版本kernel_version，找出那些還沒有安裝驅(qū)動(dòng)的內(nèi)核
$ dpkg -l | awk '/^ii.+kernel-[0-9]+\.[0-9]+\.[0-9]/{gsub(/proxmox-kernel-|pve-kernel-|-signed/, ""); print $2}'
## 手動(dòng)指定驅(qū)動(dòng)版本（在deb文件名中有體現(xiàn)）和內(nèi)核版本（從上一句命令的輸出中），zsh按tab可自動(dòng)補(bǔ)全，比如：dkms install r8125/9.011.01 -k 6.2.16-5-pve
$ dkms install r8125/<driver_version> -k <kernel_version>
## 卸載不再需要的headers
$ eval apt-mark auto $headers
$ apt autopurge
## 禁用r8169驅(qū)動(dòng)
$ echo "blacklist r8169" >> /etc/modprobe.d/dkms.conf
## 重啟
$ update-grub
$ update-initramfs -u -k all
$ reboot
## 再次查看網(wǎng)卡加載的驅(qū)動(dòng)，現(xiàn)在加載的是r8125了

每個(gè)網(wǎng)卡都用到了多個(gè)核心來處理軟中斷，效果不錯(cuò)。根據(jù)這個(gè)帖子的說法，9.011.01版本驅(qū)動(dòng)是1個(gè)rx隊(duì)列和2個(gè)tx隊(duì)列。
再看看cpu各核心的使用率是否相對(duì)均衡：
