This would be why my ISP at one point were throttling IM (that is,
Jabber), SSH and telnet? :)
Jabber was not on their whitelist, SSH was encrypted and therefore
couldn't be whitelisted through inspection (and yes, this actually
prevented large web pages loading over HTTPS), telnet the same.
When I say throttling, they actually ensured that the connection died
after X amount of data was transferred.
Thankfully they just do normal limiting now, and my speed drops for
all ports and protocols during popular hours.

I can't say I'm glad, since I don't use BitTorrent and the likes, and
I still got punished. Who decides what is a priority and what is not?
I don't believe you can judge that just from the protocols.
(Ironically during the time mentioned above I was able to download
Linux ISOs at full speed over HTTP).
PS. I just realised that ISPs aren't the original topic of this
thread, and I do want to contribute to the original topic :)
I always do a fresh install, preserving my home directory (which is on
a separate partition). Installation takes no time, and I have all my
documents and settings as before. The only thing to do is reinstall
applications as and when I find I want them.
It's a nice excuse for a fresh start every 6 months :) I also like the
