Well, having applied the patch, I can say that it
doesn't help the network/disk-io problem I've seen and others
have reported.
Problem summary:
With simlutainous disk and network IO, the
network IO is about 6kbp/sec.
System Description:
AlphaPC164/500Mhz
64Mb RAM
IDE disk
Intel Etherexpress Pro/100+ (fxp)
NetBSD 1.5.1_BETA kernel
Are folks with AlphaStation 500 & 600's, AlphaServer 800 &
1000's, Digital Personal Worstations (Miata's) and AlphaPC164*'s
seeing this problem?? (I remember another report of an
AlphaPC164LX having he problem.)
All of these systems have the "cia" iobus..
How do I go about setting the available tunables on the
"cia" bus (there are several documented in the source.. My guess
is adb, er, gdb on the kernel to change the settings..:-)
FYI: my AlphaPC64's do wonderfully on network IO..
Thanks,
Eric
