I just depends on any particular setup, and what the most limiting factor is. Sound like for you it's bandwidth, but that may not always be true, even for you, depending on how much your data changes from backup to backup and things like that.
I would argue that if you have so few machines that you can run them one-at-a-time, you should, and why not? It's clearly faster for you and in addition, keeps the server less loaded and the network less loaded. What possible advantage could there be to run them together? E.

Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
