• Limit the buffer sizes to the maximum expected message size. Buffers larger than the largest message do not provide any benefit.
• compression is experimental

In my opinion, it would make sense to compare memory usage with and without the buffer. I would guess that it makes sense to create a medium-sized buffer of about 64 or 128 bytes if we want the chat server to be inspired by real chat messages. Most chat messages in my life are rather short, while few may be long texts.

Depending on the distribution of message sizes, setting the buffer size to a value less than the maximum expected message size can greatly reduce memory use with a small impact on performance. Here's an example: If 99% of the messages are smaller than 256 bytes and the maximum message size is 512 bytes, then a buffer size of 256 bytes will result in 1.01 more system calls than a buffer size of 512 bytes. The memory savings is 50%.

That's right :) Since we want to test with several message sizes, this config might have a direct input on the services performance. In our case all messages will be the same size as well (in the scpe of one load test). I would suggest testing everything with 128 bytes. In the scope of the first load test we could test everything with a different buffersize as well, to "get a feeling" of the parameters impact.
