The CPU handles the calculations, the memory holds the data being used, and the hard drive holds the files. The three perform different tasks, and adding one does not necessarily solve the problem of the other.
Understand the essentials
Insufficient memory may slow down switching between multiple software; the disk may be full and cannot be saved; high network latency may cause it to take a long time to see a response after clicking.
A practical example
Hypothetical example: the browser slows down when opening many tabs, and there is insufficient space to save the video. These are two different directions for troubleshooting.
What to check or try
- First describe where the slowness is.
- Watch in Task Manager or Platform Monitor.
- Compare resource usage by the same task to avoid upgrading all specifications at once.
The three resources can be understood in terms of "ability to do math", "materials that can be spread out at hand at the same time" and "storage cabinet" respectively. The analogy only helps to get you started. Ultimately, you should still look at the resource requirements of the actual software. If you find the bottleneck before changing the configuration, the results will be easier to compare.
An easy-to-miss detail
The "number of cores" in the cloud is also affected by CPU generations and resource allocation, and performance cannot be directly compared with numbers alone.
