And by the way, it'd be interesting to see if those JRockit figures stay as good if you cut way back on the memory (say to 16MB, or even less for the small document test). If JRockit *is* just taking advantage of the large available memory, those performance benefits are not going to apply to server applications (where no matter how big the pool, you end up running out at some point and have to start recycling).

Nice figures from JRockit! It's interesting that basically all the times are improved with JRockit, but the amount of improvement depends on the library. dom4j still beats OM by a comfortable margin even under JRockit, though (reformatted):

I don't know why JRockit does so much better for some of the libraries. More efficient memory allocations and garbage collection, perhaps? I think dom4j has been more performance-designed than the other libraries, so I'm not surprised that it gains relatively little from JRockit on the large document run (build+walk is actually a little slower, but the JRockit write time is better). But even dom4j gains a lot on the small document test runs.

JRockit is definitely not cooperating on the attempts at garbage collection (I do repeated calls to System.gc() with waits in between, which generally works on Sun and IBM JVMs) - that's why the memory size figures are all garbage. I suspect what's going on is that the large memory size I used for the tests (512 MB initial and maximum memory) causes JRockit to mostly skip garbage collection and just use the large pool available, while Sun's JVM still does the cleanup. The libraries that generate the most garbage would gain the most from JRockit in this case, which seems to match the results. The small differences between the minimum times and average times for JRockit would also go along with this.

Incidentally, the version of the code I provided is Java 5+ only, since it uses System.nanoTime(). It's easy to tweak this to use System.currentTimeMillis() instead for older JVMs, but the precision of the timing values is naturally not as good that way.

Dennis,

what do you make of these test runs? as the name implies one is under
JDK15 the other one using JRockit.

thanks,

You might want to just add this on to the one I created, Glen:
http://issues.apache.org/jira/browse/AXIS2-533 I include JDOM in my test
code there (using the Piccolo SAX parser), but didn't discuss the JDOM
results in the text since dom4j is generally faster and smaller.

Glen,

Could up please send the bigfile.xml as well? Better to do it via JIRA.

Hi folks:

The following is a quick test which takes an XML input file, parses it, and walks the tree collecting all text content. It does this using both JDOM (note that you'll need the StAXBuilder and StAXTextModifier which you can find at http://svn.woodstox.codehaus.org/utils/jdom/) and AXIOM, 100 times each, and then averages the timings. The code is as close to
identical as I could get for the two packages.

For the file I'm working with (about 150K) I'm seeing AXIOM get an
average time around 180ms, whereas JDOM comes in at around 77ms.  The
strings match up.  This could be better, because frankly JDOM is way
easier to use. :)

I think it might be time to integrate some performance testing into our builds, and to do some optimization on AXIOM. I haven't yet looked at
comparing memory footprints, but may try to do that sometime soon.
