Frequently Asked Questions
What happens if my server runs out of RAM?
When a server exhausts its allocated heap memory, the Java Virtual Machine throws a java.lang.OutOfMemoryError, causing tick stutter, player timeouts, and server crashes.
Is CPU clock speed more important than RAM?
Both are essential. RAM holds the loaded chunks and entities, but single-core CPU frequency (like our 5.7 GHz Ryzen 9 9950X) processes all world tick calculations (20.0 TPS).
How much RAM does Paper save over Vanilla?
Paper and Purpur include advanced async chunk loading and entity pooling that reduce memory footprint by 30% to 50% compared to default Mojang Vanilla servers.
Can I upgrade my RAM later without losing data?
Yes, with SkyRainCloud instant scaling, you can upgrade your RAM tier anytime with 1-click from the game panel. All world files, plugins, mods, and player inventories are 100% preserved.
