Two things I've done to speed it up are to restrict the size of transfers (use the -o flag) and eliminate all the size checks (use the -n flag). Why would MFS be much faster than UFS? On the server doesn't the whole file end up cached? ...and the metadata changes likewise via softupdates. Running fsx during resource shortages (low memory or buf structs) has exposed a bug or two. Running it with operations 512 or page aligned also exposed bugs - see usage for those flags. Note that if you get a failure at operation 50 million there is an fsx flag which allows you to restart at, say, 49 million. Of course some failures don't reproduce reliably at the same spot anyway. I gave out fsx source code at the recent CIFS (SMB) plugfest. If I make the 2002 Connectathon I'll give it out there too. I don't test it on Windows so those defines may be in need of repair. Please send me any patches or cool additions. -- Conrad Minshall, [EMAIL PROTECTED], 408 974-2749 Apple Computer, Mac OS X Core Operating Systems To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
