I recommend Brendan's book on Systems Performance[1], describes a structured approach to solving performance problems and is a good reference for various types of resource performance profiles. [1] http://www.brendangregg.com/sysperfbook.html http://www.brendangregg.com/sysperfbook.html

Has anybody else found this book a little too high-level? I've had a hard time getting useful, practical advice out of it but haven't read it cover-to-cover yet. For instance there's a bit about the impacts of using a GC'd language, but there's nothing new, just common knowledge. Does anybody know of a lower-level/more advanced resource like this book?

  IMHO: I use it more as a reference book. "Oh, I'm having I/O problems, let me look up the sections on Filesystems and Disks" It is very dry, and hard to read from cover to cover, but it is filled with a mountain of info. I unfortunately don't know of a more introductory book to recommend, but would also be curious

    The parent asked for more advanced book, not for more introductory book.

      You are correct. <insert joke about me needing more coffee here>

  I wanted to give an overview & awareness of all performance areas, not just the focus of the book (systems). So topics like runtimes (and GC), queueing theory, etc, are summarized in less than a page in a 600+ page book. A big problem with performance is gaps in people's knowledge (unknown unknowns -- which I referenced in the intro), so I wanted to at least create awareness of them (to become known unknowns). But I bet that's frustrating if I've hit an area you want to know a lot more about. Areas like systems performance methodology I've written a lot of new material for in the book in more depth.
