Samba 4.18 merged into nightlies

[anodos]

We just inserted Samba 4.18 into the nightly builds. If you're running nightlies you may want to hold of on updates for a few days until any kinks are worked out.

Samba 4.18.0 - Release Notes

of key note to TrueNAS users:

SMB Server performance improvements
-----------------------------------

The security improvements in recent releases
(4.13, 4.14, 4.15, 4.16), mainly as protection against symlink races,
caused performance regressions for metadata heavy workloads.

While 4.17 already improved the situation quite a lot,
with 4.18 the locking overhead for contended path based operations
is reduced by an additional factor of ~ 3 compared to 4.17.
It means the throughput of open/close
operations reached the level of 4.12 again.

4.18 will be in Cobia. BlueFin will continue to have 4.17 for its lifecycle.

Any chance of NAS-118522 getting fixed with this and making it back to core?

I can evaluate that particular issue when backporting to core, but it won't be in 13.0 since we are locked into Samba 4.15 there.
