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

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
