What is better, GET data and save it or let the other app POST it and save it?

Hi guys,   We have a Mx app and PHP app (data collector). I have "architectural" question. I am wondering whether there is performance difference when getting data POSTed in our Mx app instead of GETting it from the PHP-app. I expect no difference seen POST and GET actions Mendix native functions are, but dont know what exactly happens in Mx runtime for these both actiond and whether it could imply performance wise differences.   Anyone an advise, best practices (no restricti?

My preference would be to use GET because that I can influance on my side when this occurs. When data is POSTed it can happen when my application is already doing a lot of other stuff.
