max number of producers/consumers per transport

What is the maximum number of producers/consumers that is supported per 1 transport?
Is there any scenario where it is better to have multiple transports instead of 1 transport carrying multiple consumers/producers?
Thank you

In theory: no limit.
In practice: ask the browser vendor.

No limit in mediasoup.

So even If I want to receive from different remote users I only use 1 transport to mediasoup and never multiple as it is better for the b/w estimator correct
