Pinning doesn't solve the problem of cache L3+ thrashing.

  It could if the GCs used non-temporal instructions that bypass the L3. Of course, how much of a problem this is in practice in most applications is something that would need to be measured.

    Point taken. What about swap?
    • pron 6y ago
      Yeah, swapping could be really bad and should be avoided. So: don't swap :) Java's memory consumption can't go up indefinitely. The most important setting is the maximum heap size. Set it to a good level and don't swap.
