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!
