I’ve got a new build up and running that seems like it should have a lot more oomph. And when the pool was brand new, I was seeing some 110-190 MB/s transfers briefly, but now it’s crawling along at 35-55 MB/s

network transfers seem ok:

Disk IO I’m honestly not sure how to read, but the CPU and disk seem to be sleeping.

Any help is appreciated.
I know the PERCs are not well liked, looking to find a replacement HBA, but also struggling to find out with HBA would be a direct slot in to connect to the backplane.
