Why can't we specify how many cores we get? I'm sick of having 2GB or more of RAM and only one core. Some languages can actually saturate 4 cores and use less than 2GB of RAM while doing so. Are there any CPU core friendly VPS providers out there?
- bryanlarsen 12y agoYou're not getting exclusive access to a core, you're only getting part of a core. If the host machine has 20 cores and 256 GB of ram, then you're probably getting (2 * 20 / 256) of a core. Would you rather get (2 * 20 / 256) of a single core or (2 * 20 / 256 / 4) of 4 cores? Time slicing and threading adds overhead, so you're generally much better off with a provider that pretends to give you a single core than with one that pretends to give you 4.
