Show Notes 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 Links • Atlas • Digital Ocean Tweet us your tasty treats! • Scott’s Instagram • LevelUpTutorials Instagram • Wes’ Instagram • Wes’ Twitter • Wes’ Facebook • Scott’s Twitter • Make sure to include @SyntaxFM • in your tweets
