Upstream and O3X versions

Postby monroo2 » Sat Oct 07, 2017 11:30 pm

Hi guys,

I was curious about upstream version of O3X so I've checked the wiki. But now I'm a bit confused.

According to the wiki both O3X v1.6.1 and v1.6.2 are based on ZoL v0.6.5.x branch. But in the last 2 changelog ADB and "Compressed ARC" are listed, which I thought were part of and introduced with ZoL v0.7.x branch.

Did you use those parts of the v0.7.x code, merge it with v0.6.5.x and create a custom code branch?

Also ZoL v0.7.x changelog mentions some hardware accelerations. What are your thoughts on them? Do they increase performance significantly or is it more like a "Slight performance increase in special workloads" kind of a thing? I think Gzip acceleration needs special hardware but will it be possible to integrate "Vectorized RAIDZ" to O3X? Etc...

Actually, our upstream is not OpenZFS's own repository and we no longer track ZOL directly. So we have a few new features that are not yet in ZOL.
