我正在尝试使用 systemd 服务在 Ubuntu 16.04 上启动时运行我的 minecraft 服务器。我创建的服务可以运行，但它的 CPU 使用率过高。如果我单独运行 minecraft 服务器，它的 CPU 使用率通常只有个位数。当我通过服务运行它时，它一直处于 100% 的状态。有什么办法可以解决这个问题吗？
我用来提供服务的链接：这里
systemd .service 文件
[Unit]
Description=Minecraft Server
[Service]
WorkingDirectory=/home/minecraft/world
User=user
Group=user
Restart=on-failure
RestartSec=20 5
ExecStart=java -jar spigot-1.9.4.jar nogui
[Install]
WantedBy=multi-user.target
输出：
user@server:~$ systemctl status minecraft-server.service
