RPMsg Framework queries

Hi,
I am using RPMsg Framework for Communication between Cortex-A35 core to Cortex-M4 core.
Below are my queries :
1. I have created multiple endpoints for a single channel. I have increased the buffer size (RPMSG_BUF_SIZE ) to 1024. This buffer is for Single endpoint (In single endpoint we can have 1024 bytes of data transfer) OR It is for the channel ?
2. From the documents I got to know that we even can create multiple channels. What is the advantages of having multiple channels ?
3. Can you please provide the information on Transmission rate, baud-rate and throughput details of RPMsg data transfer.
4. What is the known limitation of RPMsg framework ?
Please provide the response for the above query
Thank you,
Regards,
Sharmila d
