I’m currently using a VPS from contabo and am curious if I would get better performance CPU and disk I/O wise because of the dedicated resources. The bigger VPS from contabo seem to be in a similar ballpark to the cheapest options available in the hetzner server auction when it comes to corecount, ram and disk size and price.
Although most providers do over provision, due to mostly bursty nature of most services, you’re probably less likely going to notice the shared aspect as opposed to the general age of the system. So it may be a good idea to take a quick peek at your VPS’s processor and compare that against what you’d be auctioning for. 1 older core (I.e. E5-2687W) is not going to be able to put up same amount of work against 1 newer core (I.e. AMD EPYC 7763) — brands and actual models are less relevant, just the idea of age gap that’s more important.
If you want to be absolutely sure, it may be just a good idea to budget for some duration where you’d pay for both services (you’d need some time to migrate everything anyway), and run benchmarks on both systems to see what you’d get out of each, then decide which one to keep.
