Hello all, I haven't read the whole thread so far, but...
I would encourage some posters to cool down a bit. There are only a few types of ATA-Disks that support Tagged Queuing and they all work with Write Cache nearly as fast as with WC+TQ. I made some comparison (admittedly with a SCSI-Disk :-) between TQ and WC and I found out, that, when copying the whole ports-tree f.i., TQ and WC have nearly the same performance gain and TQ+WC adds another 10% performance... so, no big deal IMHO. Of course, safety is another point, and I prefer TQ over WC exactly because of this! But - to be honest - I prefer SCSI over ATA because of this ;-) So, in the end I think it's a at least possible decision to release 4.6 with ATA 'as is'. It's switched off by default and shouldn't frustrate any new users. It should be stated clearly and 'loud', that ATA Tagged Queuing in not working on many chipsets and that the situation is expected to improve during 4.6-STABLE. And BTW: I don't think that it's helpful to focus on that ATA TQ-Issue so hard and to imply (at least between the lines of some postings) that Soren's driver is all crap. It's obviously the best driver we *have* and obviously the most knowledgeable ATA-Programmer who's working for 'our' FreeBSD and we should appreciate that. -- Ciao/BSD - Matthias Matthias Schuendehuette <[EMAIL PROTECTED]>, Berlin (Germany) Powered by FreeBSD 4.6-RC To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
