is that really only 100 rows or are you actually talking about columns?
if the later you will have a very hard time getting reasonable bulk/mass
loading performance in most databases (and also pg) - a table that wide
and with a that ridiculous number of indexes is just bound to be slow.
Now I actually think that the figures you are getting from innodb are
fairly reasonable...
