The iSCSI provider has been rewritten for Solaris family and has considerably changed the performance. Detailed results can be seen in this blog entry, iSCSI before and after. Some of the performance gain is actually from a change in the processors and effective interprocessor communication but the software was previously the bottleneck. Here is a quick summary:
OLD:
Sun Storage 7410 (Barcelona, 2008 Q4 software)
311 MByte/s
37,056 IOPS (512-byte)
NEW:
Sun Storage 7410 (Istanbul, 2009 Q3+ software)
2.7 GByte/s
318,099 IOPS (512-byte)
