Hi Karsten,
Thank you for fast reply.
So, now more clear for me to understand.
I try to calculate average Bandwidth per User based on Data from
metrics.torproject.org and I got around 30-40 Kbps/user. but it is total
bandwidth/average daily user. if I want to calculate end-to-end
bandwidth, the result i divide 3. with assumption we have 3 relays to
establish connection (Entry, middle and exit). each relays have equal
bandwidth (only assumption, in the reality, total bandwidth for 3 relays
are different). then, average bandwidth connection is 10 - 15 Kbps.
in VoIP case, we need 30-35 Kbps (iLBC and Speex codec) to have good
quality calls.
Ah, in that case user statistics won't get you very far. I suggest you
try out whether your VoIP application works with Tor or not.

then my next question, does TOR ensure the bandwidth for users? at least
each user can get minimum bandwidth around 30 Kbps.
No, Tor doesn't ensure a minimum bandwidth per user. Again, worth a try
if the provided bandwidth is sufficient or not.
Best,
Karsten
