In this Hasty Treat, Scott and Wes talk about how to make servers fast!

If you want to know what's happening with your errors, track them with Sentry. Sentry is open-source error tracking that helps developers monitor and fix crashes in real time. Cut your time on error resolution from five hours to five minutes. It works with any language and integrates with dozens of other services. Syntax listeners can get two months for free by visiting Sentry.io and using the coupon code "tastytreat".

3:58 - Ram / Memory

Things like variables, functions, callstacks, application cache, sessions are all stored in memory
Large processes can eat up lots of memory
Reading 1,000,000 lines of a CSV
npm installing
Swap Memory
If your node application is limited by memory, it will crash or wait longer for memory to be freed up (garbage collection)
Garbage collection can take up CPU resourced
High-performance databases

7:52 - CPU

The processor on your server - the brains of the computer
A task - like 1 + 1, or function handleClick(), takes CPU time - the faster the processor, and the more cores it has, the faster it can think and perform these tasks
A faster CPU means your node app will start more quickly

9:26 - GPU

Most servers don't have a GPU
GPUs are not only good for graphics, but they are great at solving complex tasks
Bitcoin mining is fast on a GPU
Machine Learning

11:47 - Disk Space

SSD vs HDD
The files have to be read from the hard drive and served up to the web server - the hard drive speed determines how fast they can be read, and how fast they can be written
SSD is more expensive but makes for a much faster application
HDD is cheaper and is better for storing larger files that aren't as time-sensitive
An SSD will mean your node app will start faster and serve up files more quickly
