Using DTrace to Profile JDBC-Related Calls in GlassFish
By woodjr on Jul 16, 2007
How can a large project like GlassFish make such brisk strides on performance (1, 2, 3)? Well, for one thing, it certainly doesn't hurt to have backing from a company that has created tools like DTrace.
In his latest blog entry, Paul shows how he used DTrace to identify hot spots in the PostgreSQL JDBC Driver when run on GlassFish. Of course, the same techniques could be applied to any area of GlassFish. So please, feel free to jump in and help with our endless push for top performance.
