WebDec 6, 2014 · 1 Answer. The main issue is use of your L3 cache in terms of performance. I suspect your BitSets fit in an L3 cache so no matter what else you do I suggest you keep things as simple as possible. If your BitSets don't fit into your L3 cache, your only option is to by a bigger L3 cache or buy more sockets (in one machine or more than one ... http://duoduokou.com/algorithm/39751091636294386708.html chevy 8 in touchscreen
