The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

I have not done formal benchmarks but there is a noticeable difference. I have about dozen Java apps (about 50/50 mix of web apps and web services) running under WebSphere and they are always faster running in WebSphere on i5/OS using the native drivers than they are running under Tomcat on Windows with the toolbox drivers. The only performance issues I've run into with these apps have turned out to be issues with how the development was done (generally unneeded loops or queries) and I've never had to worry about the overhead of JDBC.

Booth,
I have not noticed performance issues using JDBC. The toolkit drivers are noticeably slower than the native drivers but both perform well.
Have you done actual benchmarks or is this your impression?
