"low latency tips are practices that people have found work - I won't call them 'best' practices because often they aren't. But generally the advice centered around the ones detailed here ..."
"Off-heap memory storage is useful for low latency applications, to avoid GC overheads on that data; Low latency applications benefit from 'no-copy' implementations, where you avoid copying objects as much as possible, thus minimizing or even avoiding GC"
