aix6.1安装weblogic8.1 性能问题！ 求救！！！！！！

各位大侠，请教个问题，

我在aix6.1上安装weblogic8.1 sp6 ， jdk 是ibm的1.4  64位，

在创建domian后， 查看日志有如下错误：

formance pack. Using Java I/O instead. Please ensure that libmuxer library is in
:'/usr/java14_64/jre/bin:/usr/java14_64/jre/bin/classic:/bea/weblogic81/server/
lib/aix:/usr/java14_64/jre/bin/sovvm:/usr/lib'>

ive sockets, but the maximum number of socket reader threads allowed by the conf
iguration is: 8. You may want to alter your configuration.>

请问怎么解决？？？？？？？
