Mejorar el consumo de recuros en vps?

Necesito ayuda para mejorr elp erfomance de un vps debian a 64 bits con 2gb de ram y 2 ghz de cpu en leaseweb. la web carga lento cuando eluso de cpu de apache sube al 30%,ademas el cpu no baja del 90%,no se nada de administracion de vps, leyendo vi que al ejecutar el comando top puedo ver los procesos que se estan ejecutando.estos son mis resultados

y en el panel el cosnumo de apache em sale esto

mi sitio web(no coloco el sitio por que infringe las politicas de la web) tiene unas 200 visitas cuando ocurre eso, pero cuando estuve en otro vps lso 200 usuarios los aguantaba sin problemas.

Se que hay que configurar el apacge.conf y my.cnf pero no se que parametros debo tocar ni que valores debo colocar.este es mi apache.conf

Código:
#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# The configuration directives are grouped into three basic sections:
#  1. Directives that control the operation of the Apache server process as a
#     whole (the 'global environment').
#  2. Directives that define the parameters of the 'main' or 'default' server,
#     which responds to requests that aren't handled by a virtual host.
#     These directives also provide default values for the settings
#     of all virtual hosts.
#  3. Settings for virtual hosts, which allow Web requests to be sent to
#     different IP addresses or hostnames and have them handled by the
#     same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "foo.log"
# with ServerRoot set to "/etc/apache2" will be interpreted by the
# server as "/etc/apache2/foo.log".
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE!  If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs/2.2/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
#ServerRoot "/etc/apache2"

#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
LockFile ${APACHE_LOCK_DIR}/accept.lock

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 15

Desafortunadamente no existe una opción generalizada para casos como el tuyo, lo ideal sería que un admnistrador de servidores lo chequeara y hiciera los ajustes correspondientes. logicsupport, infranetworking, ultimateservermangement, te pueden echar una mano.

Es muy raro que mysql consuma tantos recursos. Apache no parece ser el problema.

Tienes mucha memoria, asi que podrias aumentar la memoria cache de mysql para que guarde las consultas mas comunes.

GRacias eres un genio!! eso confirma tambien lo qu ehice probando con el mysqltuner.pl, parece que estaba buscando pro el lado equivocado, en las recomendacionesl del script me salio que debia cambiar este valo
query_cache_size = 32M
lo deje tal como se muestre,estaba en 16mb, y ahora el uso de cpu bajo drasticamente,recien ha vuelto a subir,pero desde que hice el cambio no ha subido a mas de 50%,solo el uso de cu de apache sigue alto,pero ya no sube hasta 117%,ya me diste uan luz de que es el mysql el que debo optimizar,con razon y en el utlmo vps tuvieron que darnos un procesador de 4 nucleos para que mejorara la carga,todo por no saber....te agradezco la ayuda

Solo de entrada... Podrias evitar usar bases de datos innodb y veras una gran diferencia.
