Hello, sorry to hijack this thread a little bit but Brian talks about "4 CPU cores" and Ben says "scale horizontally".
Just for interest - why not just use 8, 16, or 32 CPU cores? Is Go limited at a specific CPU amount or is there a disadvantage to have to many cores? I think if someone is monitoring so many devices this is enterprise network and servers/VMs with more CPUs are no problem. Ben Kochie schrieb am Freitag, 12.
