So that's why a 2 systems were getting crappy speeds. Yes, 2. It had been used only to split a single drop from another switch between two systems.
New drop, happy clients.
Some stuff here is museum material.

As someone who grew up with 10Base2 and 10BaseT, and thought 100Mbps was amazing - it still surprises me every time I'm reminded how slow it is now. I buried a cat6 cable out to my wife's studio and due to (I assume) some grounding issues it only syncs at 100Mbps - it works for general browsing etc., but every time we try to move some data it's arggghhh.
What type of cable did you use? Water could have seeped into which cause a bunch of weird issue because the resistance on the wires goes all wonky. I’m not sure if you have access to a cable certified like a Fluke, but if you do I would use that to test and it will most likely tell you your issue. I highly doubt it’s a grounding issue because you’d issues like that in large buildings where the power is on different phases or technical power.
Fast ethernet ain’t so fast these days
Shouldn’t be a grounding issue as you said that you buried it.
Can't find an emoji holding its side and laughing. Just pretend.
It's a 200' cable and the buildings each have their own connection to the power company. I suspect that the earth potential of the two buildings is quite different - I just have not figured out a way to measure it yet and not sure if there's anything I can do to fix it even if I do confirm it.
Pull a copper wire from one ground to the other?
That shouldn't be a problem unless you're using grounded shielded cable, in which case you should make sure the shield ground is only connected at one end.
Potentially I might know a Gaia that can help.
a Gaia?

The phone lines repurposed as ethernet in my parents’ house also only do 100 Mb/s. I concur, so painful. I want to put a storage server there but no matter where it’s limited by awful speeds. It also means getting faster internet would be useless because it would be limited by these wires.
I wonder if it would have been the same cost to do an outdoor fiber run.
Probably not, the costs were essentially just sticking ethernet ports on the walls next to the phone ports and rewiring the existing wires to those ports. And back when this was done (whenever we got DSL, around 2005 maybe?) fiber tech was probably prohibitively expensive. I haven’t looked up how much fiber modems cost but it would probably be more expensive even today.
I've worked at places where we repurposed old CAT3 cables for network connecting printers, desk phones, environmental sensors, etc. Rare occasions where 10Mbps works just fine. Using that to connect a PC would suck.
Buy a cheap unifi ptp bridge on ebay, speeds are fantastic and you can even put an AP at the other end of it.
I already have a pair of Ubiquiti airMax GigaBeams left over from a different project and agree - they perform incredibly well. I didn't even bother aligning mine as they did 800Mbit/s just pointed in the right general direction. A trench was being dug to the studio for another reason and cable is relatively cheap so I figured I'd drop one in. Hasn't turned out as well as I hoped. I will setup the GigaBeams one day - but the cable does occasionally sync at 1Gbps and I'm hoping that one day it just stays there :-)
