Hi I'm using Samba to share a folder from linux to a Windows client(Windows Server 2012 R2). The disk backing the linux share is pretty fast (NAS of 500+ MB/s). However, when I benchmark the IO performance from Windows machine, I can only get around 200 MB/s.Here is what I have tried so far:Set aio read size = 1, aio write size = 1, aio write behind = true (improve from 100 MB/s to 200 MB/s)Set socket options=SO_RCVBUF=131072 SO_SNDBUF=131072 TCP_NODELAY (no improvement)Can somebody help to take a look whatelse I can do to improve the IO performance? Any help are highly appreciated!
