Lenteur Lamp

romain75 · le 2 mai 2010

Bonjour,

je dépose un message ici pour des questions de lenteur.

En effet, je dispose d'une NAS SYNOLOGY DS207 et j'ai des problème de lenteur lorsque j'accède à mon site internet.

Pour prendre en compte les différents aspects de lenteur,

j'ai cherché à savoir si ça venait du réseau ou de la machine.

Pour cela très simple j'ai installé dans le même réseau une autre machine cette fois sous WAMP avec le même site internet.

Et j'ai remarqué une différence pour :

WAMP : 5,93s

LAMP (DS207) : 15,90s

J'ai essayé d'optimisé le site mais je remarque que j'ai le script de chargement qui prend le plus de temps :

WAMP : 0s (bizarre que ça soit nul)

LAMP (DS207) : 12,21s

Les ressources de Chrome m'indique que c'est du "document" mdrrr

Pour apache, j'ai mis un cache pour les images, HTML, js, css.

J'ai limiter l'utilisation de l'administration du nas synology :


vi /usr/syno/apache/conf/httpd.conf-sys

MinSpareServers 1

MaxSpareServers 3


StartServers 1

Et maintenant, j'aimerai optimiser MYSQL :


// Fichier de configuration lors du lancement

vi /usr/syno/mysql/share/mysql/mysql.server

// Une sauvegarde

cp /etc/my.cnf /etc/my.cnf.bkp

// J'ajoute les paramètres d'un fichier par défaut


cp /usr/syno/mysql/share/mysql/my-medium.cnf /etc/my.cnf

chmod 644 /etc/my.cnf

Je test la manipulation suivante :


# cp /usr/syno/mysql/share/mysql/my-medium.cnf /etc/my.cnf

# /usr/syno/etc/rc.d/S21mysql.sh restart

Stopping MySQL...

Shutting down MySQL. SUCCESS! 

Starting MySQL...

Starting MySQL... ERROR! Manager of pid-file quit without updating file.

MYSQL data dir = /volume1/@database/mysql...

Je reviens en arrière :


# cp /etc/my.cnf.bkp /etc/my.cnf                              

# /usr/syno/etc/rc.d/S21mysql.sh restart

Stopping MySQL...

 ERROR! MySQL manager or server PID file could not be found!

Starting MySQL...

Starting MySQL. SUCCESS! 

MYSQL data dir = /volume1/@database/mysql...

Les paramètres MYSQL doivent être uniquement dans le fichier /usr/syno/etc/rc.d/S21mysql.sh puisqu'il n'y à rien dans le fichier /etc/my.cnf

Le lancement de mysql se joue avec cette commande :

PID_FILE=/tmp/mysqld.pid

MYSQL_ARGS="--max_allowed_packet=8M"

${MYSQL_DIR}/share/mysql/mysql.server start --datadir=${DataDir}/mysql --pid-file=${PID_FILE} ${MYSQL_ARGS}

# MySQL daemon start/stop script.


# Usually this is put in /etc/init.d (at least on machines SYSV R4 based

# systems) and linked to /etc/rc3.d/S99mysql and /etc/rc0.d/K01mysql.

# When this is done the mysql server will be started when the machine is

# started and shut down when the systems goes down.

### BEGIN INIT INFO

# Provides: mysql

# Required-Start: $local_fs $network $remote_fs

# Should-Start: ypbind nscd ldap ntpd xntpd

# Required-Stop: $local_fs $network $remote_fs

# Default-Start:  2 3 4 5

# Default-Stop: 0 1 6

# Short-Description: start and stop MySQL

# Description: MySQL is a very fast and reliable SQL database engine.

### END INIT INFO


# If you install MySQL on some other places than /usr/syno/mysql, then you

# have to do one of the following things for this script to work:

#

# - Run this script from within the MySQL installation directory

# - Create a /etc/my.cnf file with the following information:

#   [mysqld]

#   basedir=<path-to-mysql-installation-directory>

# - Add the above to any other configuration file (for example ~/.my.ini)

#   and copy my_print_defaults to /usr/bin

# - Add the path to the mysql-installation-directory to the basedir variable

#   below.

#

# If you want to affect other MySQL variables, you should make your changes

# in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.


# If you change base dir, you must also change datadir. These may get

# overwritten by settings in the MySQL configuration files.


basedir=

datadir=


# Default value, in seconds, afterwhich the script should timeout waiting

# for server start. 

# Value here is overriden by value in my.cnf. 

# 0 means don't wait at all

# Negative numbers mean to wait indefinitely

Bonjour Patrick,

Crois tu normal qu'il faut 10s de plus au NAS pour charger une page banale?

Mon dernier post sert à montrer mon avancement et savoir où sont les paramètres qui serviront à améliorer MYSQL.

Le service LAMP du NAS est considérablement lent, pourquoi?

La seule réponse que j'ai entendu de ta part, c'est que l'on ne peut pas comparer 2 machines de puissances différentes.

Or 10 secondes, c'est tout de même énorme, tu penses pas qu'il pourrait avoir une optimisation à faire?

Ou crois-tu qu'il faut changer de machine car la seule et unique solution que tu as à apporter est la puissance machine?

Hello,

Moi je rejoins patrickH et romain 74960, Tu ne peux pas du tout comparé les 2. et pour moi 10sec c'est pas énorme.

Pour ma part j'ai un Gros site sous joomla et rien du faite de passé d'un 207+ a un 209+ j'ai bien gagné au moins 4SEC

pourtant la différence entre les 2 machine (sans rentré dans les détails) sont 300Mhz et 384Mo de ram

alors 10sec de différence entre un proc a 266Mhz et un autre surement a plus de 1Ghz + au moins 1Go de ram, je trouve pas ça énorme.

Après sincèrement nous mettre des tartine de code qui sont 'inutile' ne changera pas la réponse que l'on t'apportera.

Cordialement,
