We have been testing iscsi on one of our hosts. 22 mirrored vdev, mirroed slog, mirrored meta (meta size set to 64k), 2tb L2ARC. Sync set to always

We've always used nfs, but looking to get more performance we're testing iscsi to use vmfs6 and thick disks.

we've moved 1/3 of our load over and so far..knock on wood.... it's been perfectly stable.

Just wondering if anyone else is seeing some success?

Been running VMs on iSCSI since the days of istgt in 9.2 (the switch to ctl was an "exciting experience") - it's been very stable, even when an HBA blew up in an array nothing was lost other than the time to swap equipment and boot up again.

The biggest thing is to make sure space reclamation is working properly. VMFS6 helps with this in a big way since it's a background-job.
