You can't do the Minecraft server because of performance right?
that must be the reason seeing as java is available for just about everything these days
modern arm socs are impressive but i seriously doubt that 2 watt chip is beating the 75 watt chip it replaced
The server was a second hand server that has 32GB RAM and 2 i7 CPU's, it was made in 2015 so quite old. The Odroid has only 8GB of RAM but for my purposes that's enough, and given the power it saves it's absolutely a bargain!
If I ever need this much memory again I can just temporarily spin up something more powerful, for all other 24/7 tasks I can keep up the efficient ARM server.
it’s great that the new machine suits your needs with so little power. whatever gets the job done with the least energy and cost is almost always the best option.
we are just questioning whether its performance is truly comparable with the old one. because arm cannot replace x86 on performance per watt alone, many applications need more performance regardless of wattage. i think your old machine was overkill for your use case
Yeah makes sense! It probably doesn't although I have no benchmarks to prove it, it just is enough for me. I know this much though: even if the x86 server had the same specs (ram, GHz) as the arm version it likely still draws more power
Well, Java can call into native code. I'm pretty sure Mojang isn't doing that sort of thing, but I wasn't entirely sure they weren't depending on a subset of the JVM or a native library that is defacto standard in the x86 world.

Same, and it sounds like it doesn't... I just wasn't sure. You can also run into things like "I never realized this was using... glibc... which is on every x86 Linux computer." I don't think that's happened either though.
Interesting, good to know
Yeah it's mostly performance related. I have like 10 different websites running all at once, and while CPU and RAM aren't 100% all the time, with a heavy load I don't have enough free to do it
