Under load with 1000's of connections? Sorry, you lose. You run out of JVM before you run out of horsepower of the entire system because of Java's non-scalable I/O model.

Until these apps are re-written with NIO, and NIO is stable, it isn't possible.

(From the next response to this thread by Dave):

The FirstSQL benchmark (http://www.firstsql.com/bench12.shtml) is pure hooey. The benchmark does not test the system under load, and the FirstSQL team doesn't appear to know how to install MySQL correctly, and bow-out (see their disclaimer). Also, did they ask either Pointbase or MySQL-AB to install and tune the application to get the best results possible for their application? My guess is, no. If you're basing your opinion on these results, you're either biased or naiive, or both.

If you want to see as realistic a benchmark as possible for Java, by a third party, with participation from the database vendors, see the

E-Week database shootout at http://www.eweek.com/article2/0,3959,293,00.asp
