项目是servlet，用了hibernate，redis。压力测试发现单核cpu占用300%左右。
top命令然后ps -mp 32396 -o THREAD,tid,time 发现有很多和pid32396相似的tid
大概tid都是32200-32400，每个tid占用cpu在0.7%-2.5%，然后用jstack 32396 | grep -A 100 ，各线程堆栈如
[root@localhost bin]# jstack 22887|grep 5b63 -A 100

下：，各位大神给指条明路，感谢。
楼上二位说的我都看过了，关键是现在想找到问题在哪块代码，但是jstack打不出堆栈信息，我主要想知道这是为什么
参考下 http://blog.csdn.net/jiafu1115/article/details/8113774
看看有没有启发呢？
CPU高表明你的计算量很大。程序有大量的循环u或计算。是不是你的项目里面有很多等。
