Measuring Performance

Performance is often ignored in Rails development until it becomes a problem. If ignored too long, though, it can get very tricky to improve. It's valuable to regularly audit performance and look for hotspots or design choices that are slowing things down.

Inspecting the Logs

Inspecting the log will help identify the source of several performance issues the application may have.

The Rails application log outputs the time spent processing each request. It breakdowns the time spent at the database level as well processing the view code. In development mode, the logs are displayed on STDOUT where the server is being run. In a production setting the logs will be in log/production.log within the application's root directory.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

Solution

This solution fixes the error caused by trying to run npm update npm -g. Once you're finished, you also won't need to use sudo to install npm modules globally.

Before you start, make a note of any globally installed npm packages. These instructions will have you remove all of those packages. After you're finished you'll need to re-install them.

echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc

mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install # ok, fine, this step probably takes more than 30 seconds...
curl https://www.npmjs.org/install.sh | sh
