Copy...

No.

And there's a reason for it: Copy spends 99.99% of the time waiting for the I/O subsystem (which is m68k anyway). You gain absolutely nothing from making the copy cmd PPC native. In fact, with WOS it would actually just get slower due to cacheflushing at context switches.

Sad..

Why i talk about it, becouse now i am copy from network 90 mb file for 2:18 min. And take a look on CPU load, here is 100% of load. Well, i was think 'maybe ppc some unload 68k cpu' ..
but, as i understand problem is not in cpu ?

It's not copy that's taking 100% CPU.

For PIO IDE systems the CPU time is mostly spent poking the data to the I/O-register 16-bit as a time, assuming the network is faster than the IDE write speed, that is.

Which filesystem are you using? not that other fs will eats less CPU but i would try SFS thats is at least, faster.

SFS under FastAta.

...update...
Just for fun: my hdd put in fast ata as master, and for slave i have 8x speed cd drive. Well, with this configuration, all transfers with hdd - 2kb per second. If i plug off Cd-drive, transfers speedup to : 6.5kb per second. Well, and 90 mb file
copy from network not for 2:18, but for 2:05 :) This strange, but i think best way yo plug cd-drive on second cable.
