Is there a good book on web application performance tuning?

I would like to read how to use caching effectively, optimize my database schema and queries, apply partitioning and load balancing. There are pretty much resources on optimizing code and low-level stuff but not the other.

I've read Building Scalable Web Sites by Cal Henderson and besides a single chapter actually on scaling, which barely scratches the surface, there is nothing interesting inside.

Is there any decent book or another resource on web application performance optimization?

From stackoverflow

• It sounds like your bottleneck is the database? Is it? Then read prevayler to decide if an RDBMS provides the right architecture.

• Take a look at the Patterns and Practices Guide - http://www.codeplex.com/PerfTestingGuide

  If you are using an Oracle database, this guide may also help.
