Tomcat性能优化，tomcat7性能优化

首先当然得安装APR，过程可以参考：http://www.cnblogs.com/hackyo/p/6792349.html

//在tomcat/bin/catalina.sh中加入，如果是windows系统将export改为set并去掉后面值的双引号
export JAVA_OPTS="-server -Xms1000M -Xmx1000M -Xss512k -XX:+AggressiveOpts -XX:+UseBiasedLocking -XX:+DisableExplicitGC -XX:MaxTenuringThreshold=15 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:+UseCMSCompactAtFullCollection -XX:LargePageSizeInBytes=128m -XX:+UseFastAccessorMethods -XX:+UseCMSInitiatingOccupancyOnly -Djava.awt.headless=true"

//在tomcat/conf/server.xml配置端口，如果没有配置APR则将protocol设置为HTTP/1.1
    <Connector port="80" protocol="org.apache.coyote.http11.Http11AprProtocol"
               maxHttpHeaderSize="8192" maxThreads="1000"
               minSpareThreads="100" maxSpareThreads="1000"

               connectionTimeout="25000" URIEncoding="UTF-8"
               acceptCount="1000" redirectPort="443"
               disableUploadTimeout="true" />

//SSL端口配置（使用APR的情况下）
    <Connector port="443" protocol="org.apache.coyote.http11.Http11AprProtocol"
               maxHttpHeaderSize="8192" maxThreads="1000"

                         type="RSA" />
        </SSLHostConfig>
    </Connector>

//SSL端口配置（不使用APR的情况下）
