I was wondering, what everyone's experience was in terms of performance with the Java API. I've been doing some performance testing between two V6 queue managers running on Windows servers with 1.6 Sun JRE's and while the actual message only takes a few milliseconds to make it across, the actual java api calls seem to take a lot longer than I expected. Round trip messaging time is between 120-130 milliseconds and I'm not doing any backend processing, just doing the basic calls (conn, open, put, get, close, disconnect). No volume testing either just single messages. I've looked for performance papers to see if there were metrics on the different languages (Java, C++, .Net etc.) calls but I haven't found anything so I was looking for some testimonials.
Thanks. |

are these messages persistent?
if you are doing conn, open, put, get, close, disconnect for each message then these figures do not surprise me.
conn and open are 'expensive' calls and should be minimised where possible.

This is true of all languages, not just Java.
You also tend to see similar behaviours with most database software.

| Thanks for the replies. The info about the conn/open calls being very expensive helped out a lot, since we will be using long running processes that will connect/open and then loop through put/gets. I just ran a test for this and the put/get combination only took 7 milliseconds. Thanks again! |
