Thanks for the reply.
You are right that 30Mb is not big, but it is an increase with almost
400% ( from 8Mb to 30Mb ) and we are not inserting new data, only
updates.
We are running Firebird WI-T6.2.679 Firebird Release Candidate 2 on a
Windows XP Prof ( also we have the problem on Win98SE ). We use the
Interbase components delievered with D5 Enterprise.
It takes about 45min to update all records in a table with about 9000
records. But we are using one big transaction for this.
I did a search on the internet and found a thread with simular
problems like we have, and this was the reason for his problem,
updating records with one transaction because Firebird than needs to
hold a copy of the data for each change in the database.
Regards,
Peter
