A vital tool-box component, the CProf cache profiling system lets programmers identify hot spots by providing cache performance information at the source-line and data-structure level. Our purpose is to introduce a broad audience to cache performance profiling and tuning techniques. Although used sporadically in the supercomputer and multiprocessor communities, these techniques also have broad applicability to programs running on fast uniprocessor workstations. We show that cache profiling, using our CProf cache profiling system, improves program performance by focusing a programmer's attention on problematic code sections and providing insight into appropriate program transformations.<>
