[rabbitmq-discuss] Question on packing of Bytes into Ethernet Frame for AMQP protocol

[Michael Klishin]

Priyanki Vashi:

> For now I see that there is no packing done at all when I took trace on server side and I see individual frames for content-header (87bytes), content-body (137 bytes), basic.publish (87bytes) and basic- ack (87 bytes) so this makes total of 4 AMQP frames for 1 message and all four are just having a very small size.

Both clients and RabbitMQ itself use sockets and are not aware Ethernet framing, MTU size value
used, et cetera. MTU size can be configured [1] but it's dangerous and no necessary 99% of the time.
