My reason is different.

I thought about a server with a bunch of clients. The server almost
constantly receives data and writes to the disk.

What about setting up client to send the full collection of
measurements? The client knows all plugins and can wait for all submits
and send the whole batch at once.
The server can wait for a number of batches or for a defined time before
writing collected data to disk.

BTW: What was the reason to use unreliable UDP for data transfers?
