Where is a pitchfork when you need it ;-> Time and micro-managed priorities limit my usefulness currently, Scott is right ... Driver is just asking for it's `just deserved' mappings to the card, I put my vote with Michael with regards to the PCI system not differentiating non-prefetched (hardware) and prefetched (memory) mappings (said with an aire of pretending to know unintentional). > > > Should I hold onto this card or should I suck it up and get > > > a 3ware online somewhere? > Be a man and buy a SCSI RAID controller. The Adaptec 5400S is > all you'll ever need =-) SCSI is too expensive for many folk, that is why we made the 2400A. However, IDE looses 2ms on every access because it can not overlap commands -- much of that delay is reduced with the SCSI origined 2400A's cache/coalesce/elevator code, we see performance that has us wondering out loud about the SCSI price differential. Good luck, hope I could help ... Sincerely -- Mark Salyzyn To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
