@plaidypus You can configure the disk within the guest OS to match whatever formatting you want. I would suspect the performance gains would be included as well, but you'd have to test and verify.

I have no idea for the legacy Linux tools, they are badly coded and you can get rid of them entirely We've been using them in prod since almost a year without any issue. 1.0 will come soon but it's already very stable and safe (it's written in Rust). Our goal is to get them in all Linux distro upstream ASAP.

@plaidypus Ah gotcha, this makes sense. I second scaling out instead of up. If you're getting new hosts, I'd also keep in mind newer CPUs do have much higher per core performance (not sure what your current stuff is), so you also might be able to get away with less vCPUs and lower likelihood of NUMA spanning. Either way though I think scaling out is the better direction to go.
