Michael,
can you report us your db stat using gstat?
(use gstat -? for options)
Your record length may be long because of 200 fields.
This needs 1-16 page writes for any insert/update.
what is your disc cluster(block) and fdb file page size?
if you did convert the disc from FATxx to NTFS, you will see it
becomes unproductive 512 bytes allways,
because clever M$ programmers knows fastest of algorithyms.
