Operations

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.

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.
