Top 'user' reaches 100% many times

Actually, I have 2 questions. At this moment I am running a site which has a lot of visitors. The current server has some problems with running, and I'dd like to see if I can optimize the code to prevent having to upgrade the server.

At this moment if I type 'top' on the unix server I see
a user, a system, a nice and a idle.

The system comes at the highest on 5%, the user reaches the 100% quite often, and the Idle is what left over at the moment, going from 97.7% to 0%.

My questions:
1) When the userstat is at 100%, does this probably mean that to many users are connecting to the website at the same time, or is also possible that each user has to do many requests when reaching certain pages?

2) When the 'user' maxes out, the sites gets slow. Does Unix have a possibility to see a list with the user requests, currently processed?

NAME

       mlib_ImageMoment2_Fp - second moment

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageMoment2_Fp(mlib_d64 *moment, const mlib_image *img);

DESCRIPTION

       The mlib_ImageMoment2_Fp() function computes the second moment of each channel in a floating-point image.

       It uses the following equation:

		     1	   w-1 h-1
       moment[i] = ----- * SUM SUM img[x][y][i]**2
		    w*h    x=0 y=0

PARAMETERS

       The function takes the following arguments:

       moment	       Pointer to moment array, where length is the number of channels in the image.

       img	       Pointer to an image.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
