Performance boost in 9.10.2-U2

[Knuuut]

Hi fellows,
yesterday I've upgraded my backup machine from 9.10.1-U4 to 9.10.2.-U2. This morning I've noticed the backups (db-dumps via NFS) ran twice as fast as all the times before. I haven't done any changes on the config.

I wonder why?

Hint: The network performance may be the source of the performance boost.

Anyway, I'm very pleased by this. Thanks to the developers. :)

Hardware: Dell R520 single CPU
96GB RAM
8 SAS 4TB disks in striped raidz1
SSD SLOG
10 Gb Intel NICs

Cheers Knuuut

It may be because 9.10.2 got newer FreeBSD version. Though it is difficult to answer without deep investigation.

My install still says 10.3:
FreeBSD 10.3-STABLE (FreeNAS.amd64) #0 41eb257(9.10.2-STABLE): Mon Mar 6 17:03:14 UTC 2017

The key point there is "STABLE". Unlike 10.3-RELEASE, 10.3-STABLE is a moving target where many changes are merged from head branch after some testing period. At some point 10.3-STABLE could become 10.4-RELEASE and then 10.4-STABLE, though it won't go that way due to planned EOL of that branch and recommended migration to 11.x.

The idea is import newer FreeBSD versions on numbered FreeNAS releases and just polish on -Un updates. The import was skipped for FreeNAS 9.10.1, but we did it for 9.10.2. 9.10.3 will get switch to FreeBSD 11.0-STABLE according to that plan.

Are the jail templates going to be updated as well with 9.10.3?

Edit: Never mind, found feature request #21091 for a migration script to move from Warden to iocage so obviously jails are going to continue to be supported and updated.

 

[mav@]

That's a good question. Probably they should be updated, since FreeBSD does not guarantee binary compatibility between major branches.

@Kris Moore would probably be a better one to ask since he's the one that filed the feature request.

Yes, jails / jail based plugins are going to continue to be supported and improved in FreeNAS 9. The new iocage api is just starting to land for 9.10.3 and we are planning on doing a lot of API / cli testing with it before making it the full switch in 9.10.4. I think you're going to like it, plugins can be created with a small bit of json now, and will be far easier to keep updated. I will be posting an early call for testing once the commits are all merged and we've done a bit of internal QA.
