COMSTAR is development complete and is under test now. The packages and source are available on opensolaris and are being used by a number of people already and so far we have not had reports of any major issues. The current plan is to integrate COMSTAR into nevada build 90 which is in the beginning of May this year.
Performance depends upon your reference platform and a number of other things. The platform we use internally for performance measurement is x4500 (aka Thumper). So far we have been able to saturate a 8G FC link with 32k blocksize and CPU utilization of 22% doing Reads from the initiator (zfs raidz back end). Same is true for Writes. But when running both reads and writes together, you hit the PCI-X limit. We are hoping to run a more formal set of performance numbers soon and post the results on the project's opensolaris page.
