Simulation numbers
Size of packet: minimum and maximium size (4K)
How fast are they sent?
How often want to send message?
How many clients? Not single group. Over mixnet. Typical usage.
Sorry about the late response, here are some numbers.
Size of packet: minimum and maximium size.
Minimum: 512 bytes Default minimum: 1K Max: 4K Max with attachements: 4MB (might want to skip this one/deal with at higher level)
How fast are they sent?
Assuming user is online: 40 messages per minute
1 message per second as burst, 1 message per minute normal flow
How often want to send message?
Online up to 2-4h per 24h
How many clients?
Assuming 1M retained/montly active users. This is ~same size as Signal, order of magintude away from e.g. Telegram, roughly what we budged for in terms of user acquisiton at Status:
Online average of 1h a day, so factor of 20, i.e. 50k users client at any given time.
On a shorter time framing this is likely to be less, so we can start initially with 1K (or 100/10K) concurrent users.
Hope that's useful. In general, it might be useful to do some form or robustness/sensitivity analysis, i.e. see how the system behaves as it goes from (say) 100 to 1K to 10K users. In terms of latency, median/95/99% analysis would also be interesting.
Out of curiosity, is the simulation for this open source? What type of output are you getting in terms of performance / anonymity set etc?
