    5252== 初步处理 == 
    5353* 237.45增加了1g内存 
    54 * 准备dump一次内存看看应用占内存的大头是哪部分，resin是否可以减少内存配置 
     54* 准备dump一次内存看看应用占内存的大头是哪部分，resin是否可以减少内存配置，237.54内存快照分析：

    5578* 测试环境模拟压力测试，看看能否重现并做动态监控和分析 
    5679 * 测试环境去掉squid和resin自带缓存，50/s的索引页和100/s的readintf模拟ssi压力测试下16个小时后的系统状态，修改jsp暂时没有出现编译内存问题。线程数保持在100左右，ygc比较频繁基本上一秒一次，之所以还可以比较好的状态估计是因为测试的ssi接口相对线上情况会好很多，不会太多出现超时失败的情形。

    85 == 长期目标 == 
     108== 优化 == 
     109* 因为索引页的ssi没有走squid缓存，考虑这部分加上mc缓存以减少r系统压力 
    86110* 考虑将大部分时间不敏感的ssi转为静态发布的方式减少压力 
    87111* 报价应用前台拆分：索引服务 + SSI服务
