Hello gentlebeings! We have a strange problem with our server! We run minecraft on a dedicted i7 920 (@2.66ghz/ 12GB RAM) hosted in a decent datacenter. The server runs Ubuntu and Java 7. The two MC servers run on an installed VPS with 10GB total, while the 2nd VPS runs only the website and TS3 server. The problem: Minecraft 1.8.x (bukkits included) causes a massive strain on the CPU related to 1.7.x. Values: We run 2 MC servers - each on a dedicated core with 4GB RAM associated. - The 1.7.3 server with CB1060 and a handful of plugins (e.g. BB) uses ~15-20% of the CPU with 15-20 players. This server can easily run approx 100 players. - The 1.8.x server without any plugins uses 50-70% of its CPU with 15-20 players and hits 100% CPU with approx 25-32 players (no world generation!) The server was monitored with top and vmstat over more than 5 days, so the given values are good averages! Also theres no change when the 1.8 server runs alone. What is going on here? 1. Why is the 1.8 server code suddenly munching through server cycles like Pacman through magic pills? 2. Why arent there more server admins reporting this issue? Is it related to our server or is it a general problem?
