Scala Compilation Speed on MacBook Pros

After deciding to take the plunge and buy the new MBP 15”, I thought a little benchmarking would be a nice confirmation that my “upgrade” made sense. Most times I use my laptop for Scala development and writing my blog. I thought I’d run some tests around the Scala compilation times for some well-known projects.

Here’s how I tested each project:

1. Git cloned the project.
2. Connected my laptop to the mains (to ensure no energy saving was sacrificing performance).
3. Downloaded the world with:

sbt clean compile

1. Ran a clean compilation four times and took the average, min and max times:

sbt "set offline := true" clean compile

Scala open source projects used:

1. Scalaz
2. Spray
3. Shapeless

• Model A => 2010 15” MBP 2.4GHZ i5, 8GB, SSD.
• Model B => 2014 15” MBP 2.2GHZ i7, 16GB, SSD. (This is not the 2015 model but is pretty close to it.)
