Some notes on performance

[Joakim via Digitalmars-d]

I was googling around for information on ninja, the build system 
used by the Chromium project, when I stumbled across this 
interesting article about how it was optimized for performance:

I also read these two from that site, the latter of which I think 
I skimmed once before:

http://aosabook.org/en/llvm.html

There are a host of articles on a bunch of open source projects:

I hadn't seen these articles mentioned here, thought some of you 
might like them too.
