单独的TOMCAT做WEB服务器,后来增加APR功能,对比如下:带*号的是比较的不同结果
(第一个文件21K,第二个文件500多K,第三个MP3文件,3M多),可以看到文件越大,使用APR后TOMCAT处理性能提高也越明显.
遇到一个难题,由于TOMCAT使用了操作系统的一些东西吧,在大访问量的站点上,重起TOMCAT时会看起不来,老是说端口已经被占用.在单机上测试没有问题,这个怎么解决?
比较： [ 1 ] 到 [ 2 ]
[ 1 ] D:\Program Files\SecureCRT\download\haveapr.txt
[ 2 ] D:\Program Files\SecureCRT\download\noapr.txt
