The usual way to slow a linker down is to put all the files concerned
on an NFS-mounted filesystem (as opposed to a local disk).

The usual way to speed one up is to find a memory disk and put all the
files there.  For example, FreeBSD often puts /tmp in a memory disk.
If you have plenty of RAM, all accesses to /tmp are to memory.  Only
if you're low on RAM, do the fiel accesses actually hit a physical
disk.  I think Linux has memory disks too.  (There's also RAM disks
but those are different beasts.  If I understand them correctly, they
cannot be swapped out to disk.)
