Hi,
I'm doing some benchmarks on geoserver and I've encountered serious memory
issues on WFS.
I'm requesting lots of GetFeature request (with bbox and filters) on two
instances of geoserver (I used separately versions 2.1.1, 2.1.2 and 2.1.3).
After about 30 minutes, the performance collapses and the GC logs shows that it
corresponds to the moments when the GC can't free any more memory and take more
than 4 seconds on average to run.
Jmap command indicates that at the end of the bench, the heap is full of
"java.util.HashMap$Entry" (519 Mo), "javax.xml.namespace.QName" (426 Mo) and
"[Ljava.util.HashMap$Entry" (184 Mo). The instances of others classes take less
than 60 Mo each.
The results are globally the same on geoserver 2.1.1, 2.1.2 and 2.1.3. I'm
confused because I made a benchmark on August 9th (10 hours long) that went
well (it was on the last nightly build available at this time), although I
think this version was more recent than the 2.1.1.
Any help would be appreciated.
