Why is unraid so unresponsive while doin datatransfers?

So, its not a big thing, but i wonder..

 

If i transfer a file in windows (atleast in newer versions, with normal hardware) i would never notice it and can do other things.

 

In unraid tho, if you transfer something, everything gets slow (like goin into folders via smb) or importing files in plex, or what ever.

 

Why is that so?


Can that be fixed?


Setup is normal array with hdds (10 xfs) one parity and 2 ssd caches (brtfs).

 

It doenst really seem to be dependend if i move or copy files form or to array, or cache, as long as there is a file transfer, the server feels slow - why is that so?

Do you have dual parity?  If so what CPU do you have.    The calculations for parity2 can load older CPU’s significantly

no, like i said 1 parity. Also neither ram or CPU is over 20%. It doenst matter, as long as data transfer is happening.

Well posting your diagnostics would save everybody doing guess work ie CPU is too slow for dual parity, etc.

I haven't done much LAN file transfer in recent times, but I've never felt my server running slow unless I was transcoding 1080p Hi10p videos in software as that would usually consume all of my Pentium G4620 cores. But I can comfortably watch Quicksync transcoded 4K videos while doing SMB transfers, remotely and over a measly 25/25Mbps link (IPSEC VPN)

I've never felt my server running slow, maybe when my 5900rpm disks are really busy - like during parity check/ drive rebuild/ or mover is running.

Or when the discs spin up. but that's how all of my Linux servers feel. Snappy enough. Windows file sharing does feel smoother and faster, but I normally use terminal / scp for file management. Windows is only for browsing the shares and I stress, it is fast enough for me that I don't feel it slowing me down.
