Now some hints how to increase DyBASE performance and reduce size of used main memory.
If you database performs a lot of updates of persistent data, then the main limiting factor is speed 
of writing changes to the disk. Especially synchronous write to the disk performed by commit.
If you will do commit after each update, then average speed will be about 10 updates per second 
(this estimation is based on the assumption than average disk access time is about 10msec and
each transaction commit usually requi
