Optimizing Kohana-based Websites for Speed and Scalability

A site I built with Kohana was slammed with an enormous amount of traffic yesterday, causing me to take a step back and evaluate some of the design. I'm curious what are some standard techniques for optimizing Kohana-based applications?

I'm interested in benchmarking as well. Do I need to setup Benchmark::start() and Benchmark::stop() for each controller-method in order to see execution times for all pages, or am I able to apply benchmarking globally and quickly?

I will be using the Cache-library more in time to come, but I am open to more suggestions as I'm sure there's a lot I can do that I'm simply not aware of at the moment.

Profile code with XDebug.

Use a lot of caching. If your pages are relatively static, then reverse proxy might be the best way to do it.

I totally agree with the XDebug and caching answers. Don't look into the Kohana layer for optimization until you've identified your biggest speed and scale bottlenecks.

XDebug will tell you were you spend the most of your time and identify 'hotspots' in your code. Keep this profiling information so you can baseline and measure performance improvements.

Example problem and solution: If you find that you're building up expensive objects from the database each time, that don't really change often, then you can look at caching them with memcached or another mechanism. All of these performance fixes take time and add complexity to your system, so be sure of your bottlenecks before you start fixing them.
