The bot uses slightly more CPU than RAM (if you get the point), so first pick a VPS which is cpu-optimized, since CPU is the most important thing. Also,
- AMD is better than Intel
- The more CPU cores, the better
- Ideally, you should have a 1:2 or 1:1,5 CPU to RAM ratio, meaning, for instance, if you have a VPS with 8 CPU Cores, it should have 16 or 12 GB of RAM.
VPS providers usually have different types of VPS, so pick one which is described as “CPU optimized” rather than standard ones or for “Storage”. That being said, if you are still looking for a quality VPS, check our page with the best (cheap) VPS to run bots.
