It is not that it's =>slow -- I was prepared for that, it is that it totally hangs -- =>forever. => =>I narrowed it down to softupdates. If I disable the softupdates on =>the cartridge's filesystem copying finishes successfully. Somehow =>the `cp' process takes 150% of the CPU time (purely single CPU system), =>but that's a different story, I guess. =The drive is polling-capable only. So it makes no difference with the =cam/bio configuration. And it explains your performance result. I figured that. I only wonder if the driver can be made to poll less often -- yielding to others. But it works reliably now that I do not use SoftUpdates on it. Thanks! -mi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
