Copydev copies using the file server's block size; if it's 4K or
greater, the copy should be relatively quick. It should also report
progress so you can gauge how long it will take.
It's possible that you don't have a bus-mastering IDE controller.
Even if your disks are capable of DMA, the file server will end up
doing programmed I/O, which is much slower. Look for this message in
your file server console log:
h0: disabling dma: not on a busmastering controller
Also check that you haven't set conf.idedma to 0, like this:
fs/9fsfs.c: conf.idedma = 0; /* for old machines */
If conf.idedma is non-zero, you should see ` and IDE DMA+RWM' in your
file server log:
Plan 9 63-bit file server with 4-deep indir blks and IDE DMA+RWM
