+Throttling work by:
+1) taking note of all traffic (hooks added e.g. to connection class) and measuring speed
+2) depending on that information we sleep before sending out data (or send smaller portions of data)
+3) depending on the information we can also sleep before sending requests or ask for smaller sets of data to download
