1.Tomcat容器内的优化:端口下
 URIEncoding="UTF-8"  
  minSpareThreads="25" 
  maxSpareThreads="75"
       enableLookups="false" 
  disableUploadTimeout="true" 
  connectionTimeout="20000"
       acceptCount="300"  
  maxThreads="300" 
  maxProcessors="1000" 
  minProcessors="5"
       useURIValidationHack="false"
       compression="on"
  compressionMinSize="2048"
  noCompressionUserAgents="gozilla,traviata" 
       compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain"

        redirectPort="8443"

2.Tomcat启动行参数的优化:放在第一行后
JAVA_OPTS="-server -Xms1400M -Xmx1400M -Xss512k -XX:+AggressiveOpts -XX:+UseBiasedLocking -XX:PermSize=128M -XX:MaxPermSize=256M -XX:+DisableExplicitGC -XX:MaxTenuringThreshold=31 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC  -XX:+CMSParallelRemarkEnabled -XX:+UseCMSCompactAtFullCollection -XX:LargePageSizeInBytes=128m  -XX:+UseFastAccessorMethods -XX:+UseCMSInitiatingOccupancyOnly -Djava.awt.headless=true"
