I've renamed it to fdb but still long time for the first query after
cold boot. By the way, update a single record the first time after
cold boot is also slow.

May be. But a simple select with only one record returned should not
have many things to write to the disk.

I also worried that it was IBOConsole that caused the problem. So I
wrote a simple program in Delphi 7 using DBExpress. The result is
the same intensive disk access for the first query after cold boot.

primary key.
