dump performance - 4.6-RELEASE #0

2003-12-03 Thread Kevin Fleming

I've done numerous tests with dump and different buffer sizes etc, but the
maximum speed I can read from disk is approximately 14MB/s (measured by
iostat).

cpio / tar etc can read from disk at over 30MB/s ..

Dump seems to spawn children (presumably for better IO) - is it possible to
tweak the number of children for better IO performance.

I can write to my tape unit at a sustained 25MB/s (AIT-3 on an LVD
interface), so I'm wasting tape and time.

Cabletron PCMCIA / Nokia C910 / FreeBSD 4.7 - watchdog timeouts

2002-12-29 Thread Kevin Fleming

Problem:

experiancing 'watchdog timeouts' with Cabletron PCMCIA 802.11 radio card
(wi0). Card doesn't work as expected. Is detected Ok - but as soon as you
'ifconfig' the card - a few seconds later the 'watchdog timeout' messages
are displayed.

Configuration:

FreeBSD 4.7 - RELEASE #0
normal desktop PC with COM2 (IRQ 3), parallel port (IRQ 7) disabled.
Nokia C910 PCMCIA / PCI cradle 
Skynet (Cabletron) 802.11 radio card.
ISA VGA card
NE2000 Clone NIC  works Ok.

Tried:

moving the radio card to different IRQ and different IO address. same
problem.
Using the PCMCIA cradle (pcic0) in Interrupt mode. no differance.
Played with the hw.pcic.intr_path parameter. no differance
Cabletron card works OK in win2k laptop.

Do I sound desperate? I'm getting that way..

All the documentation / examples I've seen tend to indicate this problem is
caused by interrupt sharing. I'm almost certain this is not the case - would
like to be corrected - and make this work!

See below for dmesg output.

Please reply directly - I'm no longer subscribed to this mailling list.
