In this PurePerformance episode, Stefano Doni (Akamas CTO) illustrates how some established industry approaches and beliefs about Java Tuning are actually myths:
1) Garbage Collector tuning: do the industry guidelines and metrics always lead to better application performance?
2) Tradeoff among latency, throughput, footprint: is there a way to improve these aspects
at the same time?
3) JVM tuning or not: is it worth tuning the JVM, or is it good enough for ensuring better performance to simply use the latest and greatest JVM?
4) JVM tuning once for all: is it really a good practice to copy & paste known “good” VM configurations across different applications?
