2. Why listen to Theo?
• I wrote a book
(okay it has nothing to do with performance)
• I lead the performance and scalability
practice at OmniTI
• It’s my job to “un”break things... yes really.
• I build high-performance software.
• Why not?
• Listening never hurt, you can judge worth on your own.
3. Full-stack?
• How do you see the whole stack, all at the same time?
• DTrace
• What’s the “whole” stack? LAMP?
• Linux... err, not yet. (Mac OS X, FreeBSD, Solaris)
• Apache... yup.
• MySQL? Sure, but PostgreSQL is cooler.
• PHP... and Perl... and Java... and Ruby... and...
• anything with compiled with frames: C, C++, etc.
