I'm making a small server for me and my friends, on a Raspberry Pi. All the guides I have seen so far use Spigot, but there isn't that much documentation that I can find on what they did to make it more lightweight.
What features are lacking? Or did they just make it handle the RAM more efficient but still have 100% the same features? Can I still use the same Bukkit plugins for my server? Also, with the modifications, with a Minecraft update, do I have to wait for Minecraft → CraftBukkit → Spigot/Plugins to get all updated before I can update my server? (i.e., does Spigot lag behind CraftBukkit's update cycle?) If so, does it generally take a long time to do this?
