Hi Robert, Rumor has it that someone at JPM found the topictest faster in Java than C++ on a multi-processor machine. I've been theorizing a contention problem in the C++ code. However on an 8-way box I found the all-C++ topic test to be about 6% faster than Java broker with C++ clients and 56% faster than all-Java.
Attached are the results, test details and machine specs. Can you compare the setups? Possibly it would be worthwhile to reconfirm this result - maybe C++ got faster and/or Java got slower... Cheers, Alan.
