What's your opinion on VirMach? Can do Matrix homeservers?
Hello fellow stoned people and not so stoned people! 
I am thinking of running a Matrix server on a cheap affordable @VirMach server. They don't have IPv6, but HE.net tunnel would do fine I think. What's the word on VirMach servers and running a Matrix server?
They seem somewhat restrictive in the AUP and have some limitations on what you can/cannot do/run and I was wondering if a Matrix server might put too much load on them and they end up canceling you without refund? I see a lot of awesome deals on the Flash deals page, like sometimes up to 5-6GB RAM and 2-4vCPU for $20-30/yr.
How's their support, as in making sure everything on their end is up and running?
What kind of servers do they host your instances on?
Is the RAM DDR3 or DDR4? How old are the CPUs?
If you need to compile something that may take a few hours, could that kind of CPU consumption violate the AUP (of VirMach or any other providers really on Fair Share CPU Use)?
Thank you. Sincerely,
The stoned Guy

Could you maybe recommend some providers where we can run Matrix homeserver? Who would be a good hosts for it?
Thanks
virmach cannot ignore DMCA, if your home server has illegal files, then it will be suspended
Virmach is a bit like RackNerd. (Over)selling CC. If it's good enough for you, fine. In my opinion better give your money to another provider.
They are very strict on CPU usage.
Yes. They first kill the process, then shut down the VM. Not the right provider for CPU intensive tasks.
There's absolutely no shared environment you should be compiling shit for several hours. Get a dedicated server, FFS.
@EvolutionHost offers "100% dedicated resources".
I can compile or encode for hours without facing warnings.
After about 2 hours, it's throttled to about 30%.
The next day, I can use 100% CPU again.
Back to @VirMach , they allow 33% persistent CPU usage, sampled every hour.
If you are found to exceed 33% three times in a week, you would be warned.
Therefore, you can use 100% CPU for up to 179 minutes consecutively without triggering a warning, but wait at least 8 days before you do that again.
The actual threshold is more than 33% but @VirMach wouldn't reveal the number.
They just said 33% serves as a lower bound that you can safely use.
Nowadays I compile things on GitHub Actions, and then download the .deb packages.
When CPU usage is a concern, I use Docker or systemd to limit CPU usage to 30%.
Well sometimes you need to do dev work and for that you need to compile certain things, as repository packages are old, and emacs is my env or choice so I have to pretty much compile it from source on every box I get.
Other than webdev stuff, there isn't anything else I would be worried about compilling.
We all compile shit, but not for hours or you're doing it wrong.
Compiling the kernel will take hours.
Compiling GCC will take hours.
There's nothing wrong with that.
Their support is fine, don't expect quick responses on $20-30/year instances. If you need fast support, you can pay for it. Uptime is great, and I'm sure they'll deal with outages quickly.
The servers are all e5v1/v2 systems, but they're planning to move to Ryzen soon. Some locations are already Ryzen, like Phoenix.
RAM is DDR3, and the e5 CPUs they use are generally from around 2011-2012.
Overall pretty good provider, I idle quite a few boxes from them and use them for various projects.
Yes, get fucking dedicated resources if you're going to do that.
Their Ryzen systems are not CC systems - They own all the hardware for those.
Depends on the CPU usage. If you throttle it so it only uses ~30% CPU, it should be fine at most hosts, as long as it's just a few hours.
Most of the very cheap providers, with the exception of HostHatch and maybe a few others, do not give you guaranteed CPU usage and instead only grant "fair share", which basically means that you can't cause other user's experience to degrade by eating all the CPU.
HostHatch generally tell you how much CPU you can use for their deals, eg "50% dedicated"
For very heavy CPU usage, I'd recommend a host that has dedicated CPU, like BuyVM (on $15/month and above plans) or HostHatch (usually on 8+ GB RAM Black Friday plans), or a host that doesn't limit CPU usage (like Wishosting). Dedicated CPU like BuyVM should give you guaranteed performance, whereas Wishosting is still shared but you never get suspended due to excessive CPU usage.
Who said I don't have a dedi?
It's faster than your E5v2.
For large projects like these I sometimes spin up a very beefy VPS (large number of cores, 32GB+ RAM) at a provider that supports hourly billing, or just compile it at home on a VM that uses the same OS (or at least same glibc version) and copy the resulting binaries across.
At no point were any of your replies relevant or helpful about compiling on shared resources.
