We skipped Oracle9i as a production platform and went from 8i to 10g. We 
had a few customers who ran 9i but can't say if they had performance 
problems which were related to 9i specifically. As already suggested you 
can turn on sqltracing in the DBD and/or DBI layer. Check the 
documentation of DBI and DBD(::Oracle).  Further you could use the info 
inside the SGA to findout which queries are running real slow by either 
using Statspack of EnterpriseManager.

As a last resort you could install an instance of OracleXE, which in 
essence is Oracle10g, and see what kind of performance you get with 
that. Keep in mind though that XE has a few limitations on database size.

What I and probably the rest of the list would like to know is what is 
your hardware config and what is your software config, OS/perl versions etc.
It could be that someone knows that your config combinations is 
problematic, now we're all shooting in the dark hoping to hit the magic
