@raeburn thanks for your detailed response.
ZFS also offers compression and dedup and while it has a lot of tunables, don't recall there being a need for explicit tuning of threads (could be wrong).
the kernel version is 5.15.x... not sure how to upgrade to newer lvm tools
I have a related question. If we utilize lvm --type=vdo to create the logical volume how do we specify that we want to disable compression or deduplication. We want to...

Even if such a feature is not explicitly provided, i would imagine that the change should require modifying some constant somewhere and rebuilding the kernel modules and installing with those....
Thanks for the response. I was guessing the internal workings of VDO based upon how ZFS works. So if the file is divided up into contiguous compressed chunks, then modifying...
Thanks for the response. Then it appears to be quite different, it would also seem that this design maybe is more aligned with the natural bahavior of SSDs which do...
