Chapter 22. Project: Server Performance
Large-scale client-server architecture is ubiquitous on the Internet. Web sites may service thousands of simultaneous clients, with individual servers processing hundreds of clients. Parallelism can be achieved by multiple processes, by multiple threads within a process, by asynchronous I/O and events within a single process thread or by combinations of these approaches. This chapter explores the interaction of threading, forking, network communication and disk I/O on the performance of servers.
- Learn to measure times and control timing errors
- Experiment with server disk I/O performance
- Explore tradeoffs between threads and processes
- Use the POSIX thread libraries
- Understand different threaded-server architectures
