Downside of using one transport for only one producer/consumer?

[zaidiqbal]

Hi, I am using one transport for one producer/consumer for some of the scalability reasons on my server side and I want to stick to that.

It is mentioned in some topics that it is better to have all producers on single transport because bandwidth estimation is better in that case and I think same goes for consumers as well.

I want to ask if there is any downsides to using one transport for one producer/consumer? If yes then how much difference in bandwidth estimation, performance in percentage it will have with the other approach (one transport for multiple producers/consumers) like 5-10%?

Use always a single send transport if possible (and it’s always possible).

using multiple consumers in a single recvTransport

Yes, you should use a single transport for receiving all Consumers. That way the bandwidth estimator of mediasoup will work better than if there are N transports (so each of one would have a bandwidth estimator competing with the others). BTW we’ll release soon a new version of mediasoup with transport-cc support, which will improve dramatically how mediasoup estimates the downlink bandwidth estimation of each receiver. So yes, use a single transport for receiving all Consumers.
