CPU utlization
Hi

I have server with 48 cpus running SUN os.

I have loaded with enough tasks. But I could see my CPU utilization is very less compared to kernal's cpu utlization.

below is the output of top command

Code:
load averages:  23.2,  10.1,  16.6;                    up 423+16:45:16                                                               12:15:10
781 processes: 750 sleeping, 31 on cpu
CPU states: 39.1% idle, 12.4% user, 48.6% kernel,  0.0% iowait,  0.0% swap

 15980 cgi        1  20    0   27M   16M cpu/516   0:22  1.94% dcs_operation_m

By that we can see there were no I/O bound and swap issues.

Could anyone assist me on this.

Thanks

NAME

       cpu - A tool for user and group administration

SYNOPSIS

       cpu [OPTIONS]

DESCRIPTION

       CPU is a tool for user administration, that was initially based on FreeBSD's pw(8). This tool will allow you to administer users and groups
       on several different backends currently including LDAP and flat files. Please see the website http://cpu.sourceforge.net for more  informa-
       tion, or help improve the man page.

OPTIONS

       There are two kinds of options; options for CPU and options for CPU modules.  There are only four options for CPU, they are as follows:

       -C configfile, --config configfile
	      The configuration file to be used by CPU. The options in this file are used for CPU modules.

       -h, --help
	      Display help for CPU. If specified in conjunction with the -m option the help for that particular module is displayed.

       -M method, --method=method
	      This  is	the method of administration. Current options are ldap or passwd (passwd is not yet working). This can be specified in the
	      configuration file.

       -V, --version
	      Display the version of the software.
