Slow download speeds

Speeds are sometimes not limited to your ISP's upload. I have a 30 down / 5 up.

I have two VPN's for testing, both from my RPi-2. I run PPtP and OpenVPN.
From my school, I can access my vpn over wifi with PPtP and only get a max speed of 5 down and 5 up, because of my ISP upload.
However, when I access OpenVPN over wifi at school, I get my full ISP capabilities of 30 down and 5 up.

While at school I get these fast speeds over OpenVPN, however my home over LAN when I am testing I only get 5 down and 5 up. (Of course I access the Server through my external IP and not my LAN IP)

So three scenarios I can come up with:
1. Full access to ISP speeds can only be accessed sometimes. (Weird)
2. Somehow some external places with certain prerequisites can bypass the ISP upload. (Weirder)
3. When we run speedtest, maybe it gets confused and tests the server and not the client. (Most probable)

I realize this is an old thread, but my questions are directly related to the topic being discussed here...and I feel like posting something similar would attract negative feedback. :oops:

My question is...why aren't clients limited by my server upload speed if they're connected to my local wifi network?

For example: With my mobile phone using LTE, I can pull 10 Mbps down. (My ISP's upload speed).

But with wifi turned on while I'm at home, I can pull 60 Mbps down (my mobile carrier's download speed).

Also my local PC connected via Ethernet seems virtually unaffected.

I'm confused as to why my speed is not limited on the wifi network my VPN is being hosted on but is limited when I'm connected via LTE. Shouldn't all of my clients be limited by the 10 Mbps upload limit of my ISP?
