linux tomcat load average issue
Hello I am running a liferay application in tomcat on one of my hosted linux machine having 4GB of ram and 1 CPU.

I get the tomcat response really slow and with much digging I found that the cpu might be loaded and can be tracked with top command.

The following is the output of top command:

Code:
top - 17:07:28 up 142 days, 21:40,  2 users,  load average: 24.64, 14.98, 7.41
Tasks:  84 total,   1 running,  83 sleeping,   0 stopped,   0 zombie
Cpu0  :  1.2%us,  0.7%sy,  0.1%ni, 92.9%id,  1.6%wa,  3.2%hi,  0.3%si,  0.0%st
Mem:   4025136k total,  3880476k used,   144660k free,   242620k buffers
Swap:  4128760k total,       64k used,  4128696k free,  2538028k cached


In the above load average values I consider 24.64 is the load in last one minute.

Is it the expected or normal value??
