Thousands of Threads and Blocking I/O
This document summarizes a talk about different server models using synchronous I/O (thread-per-connection) versus asynchronous I/O (NIO). The talk discusses the evolution of server designs from simple multithreaded models to NIO-based approaches. It presents arguments for both approaches but notes that benchmarks showed synchronous I/O to be faster than NIO in some cases, contradicting common bel

How to get C like performance in Java
Understanding how Core Java really works can help you write simpler, faster applications. OverviewJava has many areas which can be slow. However for every probl em there is a solution. Many solutions/hacks require working around Java's protections but if you need low level performance it is still possible. Java makes high level programming simpler and easier at the cost of making low level programm
