[NAS] 终于找到了 SMB 跑不满千兆的原因

发表于

之前我想用一个 J1900 的小机器当简单 NAS 用, 简单开个 SMB 服务想着跑满个千兆带宽, 结果发现都是几十 MB 甚至有时候只有几 MB , 之前怀疑过 Linux 还是 Windows 系统的问题, 直到换了个网络,

之前是很大的局域网(子网掩码 255.255.128.0 ),

后来拉到自己路由器下面(子网掩码 255.255.255.0 ), 速度瞬间就稳定在 110MB/s+了,达到了理论状态,

再加上之前在大局域网下面强 CPU ,例如 i5-7500 的机子开 SMB 的话是能跑满千兆的,但 J1900 就不行,

所以怀疑是不是 SMB 对网络大小有要求,越大的网络对 CPU 要求越高,CPU 低了就 SMB 都跑不满。
