Hi My initiator HBA has 4 ports. Right now I call scsi_add_host() only once. Currently I have single queue for all 4 ports where pending scsi commands wait till interrupt handler posts response. I am trying to add more queue (one per port) to reduce some locking contention. Can I expect higher concurrency if I call scsi_add_host 4 times , one for each port. ? Is it going to work if I call scsi_add_host 4 times and will allocate queue (for pending scsi commands) for each scsi host I registered? What performance benefits can I expect, if any? There can be multiple initiators doing I/O via my 4 port initiator HBA. thankyou vks -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
