There was a change in recent-ish builds where iSCSI traffic began to be treated as synchronous rather than async. If you don't have a slog device, this will impact performance. Check your zil usage, or disable the zil and see if it helps. Also make sure wcd is set to false in COMSTAR to enable write caching. > At first I tried with dedup turned on, but the initiator constantly losed > connection to the target due to timeouts and was completely unusable - maybe > the CPU at target (Core 2 Duo E8400) could not Dedup is usually limited by memory at the target. Adding a L2ARC can help. -B -- Brandon High : bh...@freaks.com _______________________________________________ storage-discuss mailing list storage-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/storage-discuss
