NFTL Performance

i'm seeing about 5.7 seconds to write 1mb. i'm using a 32mb doc2000 on
the isa eval board, with a vanilla 2.4.1 kernel.

a more important problem that i see is that when blocks are being
flushed to the DOC, certain parts of the system (mouse, maybe others) stop
responding until the write is complete.

i think it's caused by DoC_Delay, which is called from
DoC_WaitReady. can someone confirm/deny?
