Hi guys,
I have the problem, that when I write large files (several GB, > ~5GB) the transfer pauses after some seconds of transferring data. These pauses are up to 10-20s.
I also checked iostat (zpool iostat -v 1). Even after FreeNAS has written the data from the cache to the disks, nothing gets transferred. I tried this on a new zpool and also with around 1TB of data in the pool.
The problem seems to be an issue with MacOS, Windows works fine for now.
