From the good folks who brought you the excellent Architecture of Open Source Applications (AOSA), available for free online, as a PDF, for e-book readers or as a good old-fashioned dead tree, we're now treated to a new tome - the Performance of Open Source Applications (POSA).
POSA follows the same concept as AOSA - a different authoritative figure in the open source community is responsible for each chapter, providing you with excellent insight on how some of the most popular open source applications have been designed and built. POSA focuses specifically on performance rather than general software architecture, and I've contributed a chapter on the performance related work conducted for Infinispan (see Chapter 7).
Have a read, I'd love to know what you think.
Cheers
