5 years ago 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?

How many clients? Not single group. Over mixnet. Typical usage.
