First, v.2.5.2 is buggy and very old. Replace it with v.2.5.8. You don't need any migration for this; just keep copies of your security database, firebird.conf and aliases.conf so you can copy them back into your new installation. Then, run gstat -h on the database and copy the output into your next post. (Rt-click on the title bar of the command window, select Edit then Select All. Hit enter to copy, Ctrl-V to paste into your email.) A typical reason for Delphi applications to exhibit progressive slowdowns is poor transaction management, specifically those written with long-running read-write transactions that never get committed. Garbage builds up and builds up in the database just from everyday usage, in the form of thousands of old record versions that can't be flagged "uninteresting" because of all those uncommitted transactions. You observe the slowdown in FlameRobin, isql, et al., because all that garbage is trapped in the database. You can improve that permanently by rewriting the offending application code. In the meantime, do regular sweeps or gbak backups in (gfix) shut -single mode to clear out the trash. If you are already doing that, then you probably need to do it more often. So first things first - update Firebird and let's look at those transaction statistics from the database header. HB --- This email has been checked for viruses by AVG. https://www.avg.com
