After a recent upgrade to b124, decided to switch to COMSTAR for iscsi targets for VirtualBox hosted on AMD64 Fedora C10. Both target and initiator are running zfs under b124. This combination seems unbelievably slow compared to the old iscsi subsystem.
A scrub of a local 20GB disk on the target took 16 minutes. A scrub of a 20GB iscsi disk took 106 minutes! It seems to take much longer to boot from iscsi, so it seems to be reading more slowly too. There are a lot of variables - switching to Comstar, snv124, VBox 3.08, etc., but such a dramatic loss of performance probably has a single cause. Is anyone willing to speculate?
