| Look at this chart: https://4.bp.blogspot.com/-GLc5ve5_djc/V-ysZgW6uDI/AAAAAAAAD... The worst case scenario was 5x, which was a factor of 10 off. If you are that far off when you do your capacity planning, you can be pretty sure you've got problems throughout your entire stack. |
That said, what you said is still true. If you're thinking you're going to have 100k users, you might be willing to allow a lot more data to be transmitted and/or processed than if you had 10m users. Just looking at tracker alone, having to transmit and measure distance between a dozen points and ordering them is a lot more work than checking whether a dozen coordinates are within a range and listing them in any order.
