in thread Out-Of-Date Optimizations? New Idioms? RAM vs. CPU

I've seen of useful, or useful looking books about Solaris system performance tuning - most of them printed by SUN. I've found the course material of HP Education quite useful. System performance tuning is hard, and system specific. I would distrust any book that claims to discuss system performance tuning without focussing on a specific OS. I'd also distrust any "cookbook".

Go for something that spends a lot of time analysing performance problems, that discusses performance measuring tools (like glance for HP-UX), and goes into detail explaining how the system works.

    I was actually considering a few Solaris books, I'll check them out.

    Thanks for the informative (as usual) advice :)

[Corion]: choroba: Yeah, but handing off the request to Dancer,Plack, Mojolicious,LWP is easy once I have the data filled into some structure ;))
[choroba]: Algorithm::Loops
[Corion]: choroba: I'm using that to generate the permutations, but I don't know how the user can pass the intended values to my function in a sane way
[Corion]: I have a prototype that permutes the get_parameters, but the values used for the get parameters should be different from the values used for the headers and potentially for parts of the URL
[Corion]: But yes, in general, my approach will be "split the URL into another set of parameters, generate an array of allowed values for each parameter and then NestedLoops() over the set"
[choroba]: hmm... so you need something like bag from Test::Deep, but not for checking, but for generation
[Corion]: This has the dual use of easily requesting sequential URLs and also being suitable for testing
[Corion]: For testing, I want to skip all tests with the same value(s) once one test fails to cut down on the number of failing tests
[Corion]: choroba: Yes, in a way I
