Hi, Daniel,

Are you using "COPY table FROM '/path/to/file'", having the file sitting
on the server, or "COPY table FROM STDIN" or psql "/copy", having the
file sitting on the client?
From our tests, having the file on the server can speed up the things by
factor 2 or 3 in some cases.
Also, using BINARY copy may give great benefits due to lower parsing
overhead.
As you say you're I/O bound, spreading tables, indices, wal and input
file to different spindles won't help you much.
