配置：Intel Xeon E5 2.4G*6核，16G内存,Redhat Linux X64，jdk 7(server),tomcat 8.9
改了tomcat 内存配置，开启了nio+epoll，结果仍不好看。。。
vi bin/catalina.sh
CATALINA_OPTS=‘-Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.EPollSelectorProvider‘ JAVA_OPTS= -Xms800M -Xmx1500M -XX:PermSize=128M -XX:MaxPermSize=300M
vi conf/server.xml
<Connector port="7080" protocol="org.apache.coyote.http11.Http11NioProtocol" connectionTimeout="20000" redirectPort="7443" compression="on" compressionMinSize="2048" noCompressionUserAgents="gozilla,traviata" compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain"/>
采用jfinal+beetl模板，apache ab压力测试结果：

未采用beetl，apache ab测试结果：

麻，再改进一下，估计能到2000多，曾听某网友说，调优后的tomcat项目能到3000，不知道是怎么做的。。。
哪位亲给说说。。。
亲们，你们的tomcat并发能到多少？,布布扣,bubuko.com
