I don't have any benchmark results handy, but a factor of 5 improvement for
a compile should be a _very_ conservative expectation, and a factor of 10 is
probably closer to the mark.  Use of ramdisks, and/or the extended memory
cache software supplied with the board, will help a lot with those slow disk
accesses too.  For what it's worth, the Inboard gets a 16.6 computing index
from the Norton 4.0 SI.  And the best news of all is that the price of the
board and its piggyback memory boards has recently come down - you can now
pick up an Inboard for <$600, and the 2 Meg daughterboard populated to 1 Meg
for <$350.
