Slime Worlds were designed by @Hypixel for a better way to handle skyblock worlds.
While vanilla worlds are designed to be efficient in large scales, they are terrible
for skyblock worlds. Slime Worlds however are more optimized and efficiently for this.
By installing the module, each island will be on its own slime world!
Troubleshooting
Auto save causing lag
You can adjust the interval of auto saving of worlds in bukkit.yml file like so:
# bukkit.ymlticks-per:autosave:6000
This will make the slime worlds saved every 5 minutes.
