# Drupal performance

## Lots of performance talk
## Not enough in-context data

---

# Faster
# !=
# Better

## Most performance improvements come at a cost

---

# Site performance

## *Requires* an understanding of your requirements and content

---

# Know your bottleneck

## This *requires* measuring

--- 

# Don't reason about bottlenecks

## If you don't measure, you don't know when you're wrong!

---

## I don't care what you *think* the problem is

# JUST MEASURE IT

---

# Let's measure some things!
