July 23, 20232 yr Hello, my server is running version 6.12.3. I have an array with parity and several drives. I also have a handful of pool/cache pools. For one of my pools im using an ssd with ZFS as a writecache for media files. The share is set to use the Writecache as its primary storage and the array as secondary storage. When I write files to the share, the write speeds are very slow usually around 4 MB/s sometimes it gets up to ~35 MB/s but thats as fast as Ive seen it go. On other cache only pools using ZFS and BTRFS the write speed is as fast as I can send it via ethernet (115 MB/s). Is there perhaps some new configuration needed for using a write cache in unraid 6.12? or maybe I have just configured something wrong. I am attaching a picture of my share settings and any help would be appreciated.
