Documentation Complexity #2

Closed ellieschieder closed 6 months ago

ellieschieder commented 6 months ago

Hey, Did I miss interpret the following or should It state 1.000.000 instead of 100.000?

The maximum value of 100,000 is a good start for most systems. Adjust these values to your needs.

Hey, the documentation correctly states 100,000 iterations as a good start. The actual settings need a bit of experimenting with your use case and typical end-user devices. Be aware that even 100,000 iterations can take 30 seconds to compute on a low-end Android device. There's no benefit of making the computation too complex if you're just using it in a simple contact form on a website. Some other use cases might require more complexity, but as a rule of thumb, a lower number is better.

Thanks for the fast replay.

Yes. I understand that point. My question was more of -> should it say maximum or minimum. Sorry for the confusion.

The minimum can be 0 (still requires one iteration on the client). But if you choose 100,000 as the upper limit, I would go with 10,000 as the minimum.
