My first question would be, do you need 16GB of heap, thats a lot and
will contribute to long pauses, what happens if you try it out with 8GB,
are you trying to be too greedy with the caches ?
You question is very open ended, tuning a GC is an art from, what works
for one workload is often qui
oblem with Lucene/Solr itself.

question is whether the GC delay is being caused because your JVM
heap is too small (thrashing) or too large (long GC elapsed time.)

Is that a 4 second or 0.4 second wait?
You can benchmark the different collectors yourself.
CMS is probably the best choice.
If you have more heap than you need, then the collections will be longer than
necessary. At some point, the collector has to look at all of the heap and that
is slow. T
