Advanced Java Optimization Techniques picks up where standard Java performance tuning recommendation leave off. The optimization methods described in this book are a direct result of the author's personal (and painful) struggles with writing extremely high performance Java code. The book is divided into four section: improving I/O efficiency, reducing memory usage, getting better concurrency, and improving code efficiency. Many pages of valuable code are provided for your reuse. Most optimizations come with before/after code and show actual elapsed time improvements.
