代码优化，减少不必要的加载程序，减少日志输出 主要还是计算机本身的性能强

[kampoo]

默认配置下tomcat也只需几百个毫秒（不到1秒）就可以启动，用于日常开发测试是够的，基本不需要等待。觉得性能方面： 1- 最要紧的是一台主流电脑。如果企业配置的电脑是古董，基本上代表了这个企业垂垂老矣~ 2- 如果已经安装了其他webapp的tomcat，注意移除不必要的webapp，仅保留当前开发需要的webapp； 3- 自己开发工作需要的webapp如果有明显的性能问题，注意仔细排查，一般是网络连接问题、数据库任务问题等。

14秒也挺好的，减少加载的项目、减少项目的加载配置，加大服务内存，强化机器配置

[GOon_star]

减少打印log 主要还是加载项 如果你的加载项多肯定会耗时间的
