我的Tomcat需要很多时间才能在服务器中部署我的项目，如果只是关闭并启动我的项目需要5分钟，但是如果我更改war文件，则需要近30分钟来部署和运行我的项目，
我在我的catalina.out中看到这个警告，它与我的雄猫工作缓慢有关吗？

我把我的战争文件放在webapps文件夹中，我使用Apache8-0-45
我的雄猫有什么问题？ 如何让我的雄猫更快？ 如何修复此内存泄漏？
ps：昨天当我搜索时，我在互联网上看到我应该把这一行放在上下文中.xml我做到了.它使它好一点，至少我猜！

ps2：我是使用雄猫和服务器的新手：|
ps3 ：我读了这个[链接]并测试了它，这不是代理问题，我认为。
ps4：这个项目非常大，有很多疑问，所以我不能把它们带到这里！ 不幸的是：/
