Hi, I have speed problem

My transfer speed via shares (samba) is around 40 mb

When i test with iperf3 i get 90 mb (939 Mbits/sec)

I use an ssd cache device

what could be the problem

 

p.s.

my network setup is 1Gb (routers, switches, nics, etc.)

40MB/s is about write using default writing mode to the array, is that what you're doing? If yes see turbo write.

But are you writing to a cached user share?

Also, if using the cache device, try transferring directly to the array with turbo write enable, some SSDs are slower than people expect.
