Subject Re: Tomcat Service and OCI

I tested the performance years (3+) ago trying to answer the same 
question. In most cases the OCI driver was faster but in some tests the 
thin driver was faster (IIRC the results from that long ago).

That being said - the performance difference in the drivers is (most 
likely) negligible compared to all the other issues that can slow a 
request down.

their documentation there isn't much difference between OCI and THIN, the 10g THIN driver
now supports what OCI used to have advantage over.
