Not sure how you do that on a 1-5 mb link.
At least you said it was no different.
Teams or zoom won’t work well at that speed.
Jira or Service now definitely won’t like it.
I get 100+ down and 12-15 up (sometimes up to 20). Worse in heavy rain but that's pretty rare and still doesn't impact me noticeably. It is for sure faster than my DSL was.
I started with a Commodore 64 and a 300 baud modem in high school, so maybe my standards aren't as high as yours
But seriously, nobody has noticed (that they mentioned anyway), and all the dev tools I use over the VPN work fine - git, remote VMware desktops, etc... I use Zoom several hours a day, Teams a few times a weeks, and occasionally Skype. And personal video calls over Facetime and Signal work fine.
