万兆内网拷贝到ZFS池掉速是什么原因?

Featured Replies

交换机:兮克SKS7300-8GPY4XGS(管理型4个光口万兆)

万兆网卡:Mellanox MCX4121A-XCAT

光纤线:Finisar SFP+AOC

主板是z690和z790的ROG,内存都是128GB,CPU是13600和13700。

台式机WIN11和UNRAID,网卡和光纤线都是相同的

台式机WIN11是SSDSN750 2TB

UNRAID是8块银河16TB建立的ZFS raidz

UNRAID版本6.12.10

台式机往UNRAID的ZFS拷贝,开始是1GB满速,到10%左右就掉到300MB/秒左右,一直到拷贝完毕。

拷贝的文件是单个的电影视频文件.mkv是几十个GB左右的。

局域网的万兆设备对万兆设备(都是SSD硬盘的情况下)满速

万兆设备对2.5GB设备(都是SSD硬盘的情况下)满速

唯一万兆设备对万兆设备(UNRAID的zfs里面拷贝掉速)

台式机WIN11和UNRAID的iperf测试大概在7-8GB左右(测试了两个小时)

万兆(台式机固态)对万兆(UNRAID 阵列或缓存都是固态)
