applications.

it doesn't effect so much.
don't to accuse primary index rapidly, my example performance was
about indexed table.

what is your record size?
what are you saving in rows? divx film, mp3, mp4, jpg blobs?

i think you have some problems with your HW or SW systems other than
FB.
100 Mb means, more than 12MB second. even you have 1KB rows, you can
send 10,000 rows per second in the lonely nights, not 100!
