Whether that 12GB heap size is for Solr itself or for your client code,
with a heap that large, you should be doing more tuning than simply
turning on G1GC.  I have spent quite a lot of time working on GC tuning
for Solr, and the results of that work can be found here:

I cannot claim that these are the best options you can find for Solr,
but they've worked well for me, and for others.

Thanks,
Shawn
