You might not see the same performance improvements. The reason being
is that it's not the only performance improvement in FB 1.5. Let me
name a few improvements other than the indexes on the system tables:
improved optimizer for data retrieval, sort files uses physical RAM
before HD, tweakable thread scheduler(so that a long running query
will not slow down another connection), improved memory management,
short-circuit boolean evaluations of the WHERE clause conditions(FB
1.0 and Interbase does a full boolean evaluation).
