Are you sure about the +100 part? The 68k mirror tasks run at priority 2
and 3, which allows the PPC client to run at full speed. Note that these
tasks are not just used for file i/o - they're used for timing measurement
too.
How do you know they're using 98% of your 68k cpu time? I certainly haven't
noticed any slowdown here. "A few seconds every 5 minutes or so" seems a bit
extreme - those tasks should only ever run for fractions of a second at a
time. So, if it's taking longer than that then there must be a problem
somewhere. Perhaps you could send me your dnetc_ppc.ini file so I can see
if anything in there could be contributing to this.
