Friday evening syndrome struck me it seems: I missed the fact that you're talking about Akka IO, and not cluster messages.
For that case 7KB indeed is not much. Are you sure the messages Write messages you issue should be causing larger chunks to be written? The setting responsible for the size of chunks we write and read to the kernel is akka.io.tcp.direct-buffer-size which defaults to 128KiB. You can also enable akka.io.trace-logging which will show you exactly how large chunks are being written.
