What about benchmarks? #494

Why does nanoid lose out in terms of the number of operations per second to uuid? image

Before that, it was the opposite: image

And a question. Have there been any comparisons and benchmarks in postgresql using nanoid and 128-bit UUID. I just don't understand if it makes sense for me to use this library other than short id?

Because uuid uses built-in UUID generator from Node.js, which is more memory efficient because it was written on C.

Nano ID has 2 reasons to use it over uuid:

  1. Smaller JS bundle for browser.
  2. Shorter IDs, which could be important if they are visible for users.
