Weird problem with read and write at the same times

[cyan]

I always do queue while file transfer (move) being done in the background.

Sometimes if I click certain folder (usually with a lot files in it), opening folder take 1-2 secs and

the file transfer seems stuck for 1 sec before work normal again.

Is it a normal behavior or something wrong with my unraid setting ?

I don't use cache.

 

Thanks.

Maybe it's waiting for a drive to spinup?
