| Each VPS comes with gauranteeed RAM, and Burst RAM. The gauranteed RAM is what you're VPS will use, whether it's busy or not. It's your own memory. Burst RAM will allow the VPS to bust, or spike, above that gauranteed RAM, set to the burst RAM limit. So, if your VPS has 512MB gauranteed RAM, and 1024MB burst, then it will always use at least 512MB RAM, and if needed spike up to 1024MB RAM. P.S. We make sure the dedicated servers have more than enough resources for a VPS to burst if needed, and to quickly upgrade with more memory or hard drive space |
