Subject index vs page size
Author Nick Upson

I have a large 100Gb+ firebird 2.5 database and I'm trying to deal with some performance issues.

One indicator I have found is that several large tables have indexes with a depth of 3 (and one of 4). The guidance I have seen says to increase the page size until the depth is below 3 but the pagesize is already maxed out at 16k. Can anyone suggest other actions I could take.

Kind Regards,
