tomcat优化-有改protocol 和 缓存 集群方案 转载自http://passover.blog.51cto.com/2431658/732629

在线上环境中我们是采用了tomcat作为Web服务器，它的处理性能直接关系到用户体验，在平时的工作和学习中，归纳出以下七种调优经验。 1. 服务器资源     服务器所能提供CPU、内存、硬盘的性能对处理能力有决定性影响。     (1) 对于高并发情况下会有大量的运算，那么CPU的速度会直接影响到处理速度。     (2) 内存在大量数据处理的情况下，将会有较大的内存容量需求，可以用-X

TOMCAT优化

Tomcat是我们经常<em>使用</em>的 servlet容器之一，甚至很多线上产品都<em>使用</em> Tomcat充当服务器。而且优化后的Tomcat性能提升显著，本文从以下几方面进行分析优化。           一、内存优化         默认情况下Tomcat的相关内存配置较低，这对于一些大型项目显然是不够用的，这些项目运行就已经耗费了大部分内存空间，何况大规模访问的情况。即使是本文中的这个只有
