> I wanted to understand little bit more about AMQP, rabbitmq and pika client capability of packing of AMQP bytes into one single ethernet frames before transmission through ethernet connectivity.
> 1) What is the default behavior of pika clients and rabbit server when it comes to packing of bytes into one single ethernet frame ?
> 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.
> 2) Can we change this ? and if yes, how to change it on server side?
> 3) Does python-pika client supports such packing of bytes ? if yes, how to do achieve that also ?
Both clients and RabbitMQ itself use sockets and are not aware Ethernet framing, MTU size value
used, et cetera. MTU size can be configured  but it's dangerous and no necessary 99% of the time.
