In addition the advice from csorhand and looking at your processes it appears that you are using a LAMP configuration, so there are several things to take into account here (I am assuming the php part).
1. Examine your content, if you are serving pages that contain mixed content such as images and javascript along with dynamic php content, you might benefit from adding expiry to the static content, if client need to download less that will reduce some of your load.
2. Install a php cache such as xcache, eAccelerator or APC.
3. Look at this thread https://www.unix.com/web-programming-...primer-sh.html and use the tools linked to check your mysql configuration. I believe it is actually your communication with MySQL which is causing you the most problems.
4. Ensure that you have dns lookups turned off in apache:
Also check for "bad" pages that have nasty queries. We has on module on this site that put millions of rows in one db table, and tried to query that table every time specific pages were loaded. The server was running flat out for a few days until I managed to spot the strange behavior and truncated the table. The load went down instantly to a normal level.
CPU usage: PS versus TOP - Different output
Hi
When monitoring a Linux environment with PS command, reported CPU value for a certain process differs, sometimes greatly, from the value seen in TOP.

I am running a Dell PE R815 with 4 x AMD 12 core CPUs with 128GB of RAM and a RAID 5 array of 6 SAS disks. This is an HPC application and is definitely CPU bound, however once I run 16 of these processes (thus pinning 16 cores) the work performed slows down dramatically, to maybe 5 or 10% of what...

XmDropSiteConfigureStackingOrder(library call) XmDropSiteConfigureStackingOrder(library call)
NAME
XmDropSiteConfigureStackingOrder -- A Drag and Drop function that reorders a stack of widgets that are registered drop sites
SYNOPSIS
#include <Xm/DragDrop.h>
void XmDropSiteConfigureStackingOrder(
Widget widget,
Widget sibling,
Cardinal stack_mode);
DESCRIPTION
XmDropSiteConfigureStackingOrder changes the stacking order of the drop site specified by widget. The stacking order controls the manner in
which drag-under effects are clipped by overlapping siblings, regardless of whether they are active. The stack mode is relative either to
the entire stack, or to another drop site within the stack. The stack order can be modified only if the drop sites are siblings in both the
widget and drop site hierarchy, and the widget parent of the drop sites is registered as a composite drop site.
widget Specifies the drop site to be restacked.
sibling Specifies a sibling drop site for stacking operations. If specified, then widget is restacked relative to this drop site's stack
position.
stack_mode
Specifies the new stack position for the specified widget. The values are XmABOVE and XmBELOW. If a sibling is specified, then
widget is restacked as follows:
XmABOVE The widget is placed just above the sibling.
XmBELOW The widget is placed just below the sibling.
If the sibling parameter is not specified, then widget is restacked as follows:
XmABOVE The widget is placed at the top of the stack.
XmBELOW The widget is placed at the bottom of the stack.
