How (Not) To Measure and Profile Java Performance
Today, we all benefit from the sophistication of modern compilers and hardware, but that extra complexity can also make it difficult to reason about performance.
Concurrency Concepts in Java
Unlike earlier languages, Java had a well-defined threading and memory model from the beginning. And over the years, Java gained new packages to help solve concurrency problems.
Despite this, Java concurrency is sometimes subtle and fraught with peril.
Java Performance Puzzlers
Everyone worries about performance but few of us have the time to truly understand it. Fortunately, our modern JVMs and CPUs are capable of some amazing performance tricks, but those same tricks only make reasoning about performance that much harder.
