So after the consecutive muck-ups slingshots end, we've now hit another problem;

My friend on Unlimited, gets better performance than me on a Capped plan. During peak and offpeak hours, he lives only up the road.


During the day from whenever I get up (5ish am) my internet runs like a dream doing above 250kb/s (often maxing out my line). However, from about 4.30-5pm onwards (which is normally when I get home but I was lucky enough to test my connection today while off sick), performance is limited to the point I believe it is managed by Slingshot, down to max 250-300 if I'm lucky.

I'd like to know just what exactly is going on, when my friend on the unlimited plan gets better performance than me on a capped plan, when we both have very similar line speeds (within KBPS of each other). Can someone explain the logic to me?

My downloads start off at a low speed and speed up to 900, sometimes near max line speed before slowly coming down to the "limited" speed. I'm not really inclined to believe this is because of "Congestion" as some put it because looking at a graph over the last few hours, my speed has been consistent at just below 3mbps.


While I understand speed is not something that can be promised, surely this is too greater drop to be classed as negligible? If it stays like this too much longer, I'll be breaking contract and heading off somewhere else.

EDIT: I would like to say though, the staff I have spoken to at Slingshot when I can actually get through to them, have so far been fantastic. I'd say they're under staffed though with the wait time involved on hold.

EDIT2: While I had a couple (2) of international downloads going which took up my 250Kb's, I couldn't even load the speedtest.net website to do a test as well as a couple of others.
