Question : Copied oracle schema is slow

I have asked my "oracle DBA"  (used very losely) to copy the contents of a schema into a new schema.  They have done so, but now my application runs extremely slow.  The schema is on the same database, and all the Tables, procs, indexces (everything from what I can see) are there.   The data is exactly the same as well.

It is not my application (of course not) as I have tested it against the the old schema.

Any idea what my "oracle DBA" has done to cause this performance issue?

Cheers

Maybe there are statistics missing for new schema? Try

exec dbms_stats.gather_schema_stats(user);

as newly created user (or any other method You use to grab statistics)
