Performanceprobleme

[löschfinger]

Wir haben leider im Moment sehr stark mit der Permance unseres Servers zu kämpfen.
Ein kleiner Überblick unseres Servers:

Hosteurope:

VPS Linux XL 2.0
512 MB RAM
http://hosteurope.de/pics/tabspace5x5.gifgarantiert
896 MB RAM
http://hosteurope.de/pics/tabspace5x5.gifdynamisch
30000 MB
http://hosteurope.de/pics/tabspace5x5.gifSpeicherplatz
1500 GB Traffic
http://hosteurope.de/pics/tabspace5x5.gifinklusiveDas Forum wächst kontinuierlich. Im Moment besuchen uns täglich zwischen 30 - 120 Benutzer (inkl. Gäste). Leider geht die Performence unseres Servers in den Spitzenzeiten ziemlich in die Knie. Weitere Maßnahmen werden wir ergreifen:
Aktive Benutzer anzeige deaktivieren etc.

Nun, es wäre Interessant zu erfahren woher die Perfomanceeinbrüche kommen? Ich vermute das es am zu wenigen Arbeitsspeicher liegt?
Aus den Statistiken des Servers werde ich leider nicht schlau. Die CPU Last dümpelt nur so vor sich rum. Eine weitere Anzeige liegt allerdings ständig bei über 90% eher sogar 98,99%... (Ich kann es jetzt nicht ausm Kopf sagen, da ich momentan auf der Arbeit bin und kein Zugriff auf den Server habe).

Jetzt bräuchten wir auch paar Tipps ob es reichen würde evtl. auf einen VPS Linux XXL 2.0 (http://hosteurope.de/produkt/VPS-Linux-XXL-2.0) zu wechseln bzw. was würdet ihr empfehlen?

512 MB Ram sind eigentlich für die Grösse des Forums mehr als ausreichend.

Ich hab 1024 MB Ram und hab im Schnitt 16.000 Hits pro Tag bei ~800 Aktiven Usern pro Tag zzgl. Gäste und Spider.

Ich Tippe bei Dir eher auf eine schlechte Konfiguration des Apachen.

Oder der Server auf dem die VPS (Vrtuozzo ?!?) läuft ist Hoffnungslos
ausgelastet.

VPS sind ganz nett wenn man erste Erfahrungen mit Serverbetriebssystemen online sammeln möchte.

Bei mir lohnt sich schon der Einsatz eines dedizierten Servers.
Kostet allerdings auch einiges mehr.

Ausser man entscheidet sich für Billighoster wie S4U & Consorten.

Schau Dir mal die Config Dateien des Apachen mal an und Poste die ggf. mal hier.

Ich vermute, dass bei dir mehrere Probleme gleichzeitig die Performance negativ beeinflussen:

512 MB Ram klingt viel, aber wenn man bedenkt, dass in dem Server evtl. mit 4 oder 8 GB Ram also 8 oder 16 VPS gehostet werden, ist klar, dass der Speicher zwar zur Verfügung steht, aber die Anbindung des Speichers oder der Festplatte der Flaschenhals des ganzen Servers ist.
Selbst wenn du deine Belastung um die hälfte oder mehr reduzierst, gibt es noch die 7 oder 15 anderen VPS auf dem Server, an denen sich nichts geändert hat, sodass die Belastung des Servers kaum weniger wird.Daher rate ich dir, dass du dir entweder einen kleinen Root/Managed Server mietest, oder einen entsprechend leistungsfähigen Webspace suchst, bei dem dann schonmal nicht 8 bis 16 Betriebssysteme auf dem Server die Festplatte und die Speicheranbindung verlangsamen.
Wenn du Interesse hast und dich bei mir meldest, könnte ich dir Premium Webspace oder Managed Server anbieten.

@Schraubbär thx schon mal für dein Hilfe. Hab auch vergessen zu erwähnen das wir einige Add On´s & Hacks benutzen. Unter anderem:

vBSEO
iTrader
Paar kleine Hacks


Hier mal die Config Datei:

#
# /etc/apache2/httpd.conf
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs-2.0/> for detailed information about
# the directives.

# Based upon the default apache configuration file that ships with apache,
# which is based upon the NCSA server configuration files originally by Rob
# McCool. This file was knocked together by Peter Poeml <poeml+apache@suse.de>.

# If possible, avoid changes to this file. It does mainly contain Include
# statements and global settings that can/should be overridden in the
# configuration of your virtual hosts.

### Global Environment ######################################################
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests.

# run under this user/group id
Include /etc/apache2/uid.conf

# - how many server processes to start (server pool regulation)
# - usage of KeepAlive
Include /etc/apache2/server-tuning.conf

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
ErrorLog /var/log/apache2/error_log

# generated from APACHE_MODULES in /etc/sysconfig/apache2
Include /etc/apache2/sysconfig.d/loadmodule.conf

# IP addresses / ports to listen on
Include /etc/apache2/listen.conf

# predefined logging formats
Include /etc/apache2/mod_log_config.conf

# generated from global settings in /etc/sysconfig/apache2
Include /etc/apache2/sysconfig.d/global.conf

# optional mod_status, mod_info

Include /etc/apache2/mod_mime-defaults.conf

# set up (customizable) error responses
Include /etc/apache2/errors.conf

# global (server-wide) SSL configuration, that is not specific to
# any virtual host
Include /etc/apache2/ssl-global.conf

### 'Main' server configuration #############################################
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <VirtualHost> definition. These values also provide defaults for
# any <VirtualHost> containers you may define later in the file.
#
# All of these directives may appear inside <VirtualHost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#
Include /etc/apache2/default-server.conf


# Another way to include your own files
#
# The file below is generated from /etc/sysconfig/apache2,
# include arbitrary files as named in APACHE_CONF_INCLUDE_FILES and
# APACHE_CONF_INCLUDE_DIRS
Include /etc/apache2/sysconfig.d/include.conf


### Virtual server configuration ############################################
#
# VirtualHost: If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs-2.0/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.
#
Include /etc/apache2/vhosts.d/*.conf


# Note: instead of adding your own configuration here, consider
# adding it in your own file (/etc/apache2/httpd.conf.local)
# putting its name into APACHE_CONF_INCLUDE_FILES in
# /etc/sysconfig/apache2 -- this will make system updates
# easier :)

Hallo,

wie ist die Geschichte denn ausgegangen ? Bin im Moment am überlegen ob ich von einem 1und1 V-Server zu Hosteurope wechseln soll, da die Performance bei 1und1 mehr als bescheiden ist. Hatte eigentlich an genau den Linux XL 2.0 gedacht, da er genau in meinem finanziellen Rahmen liegt.

Wenn´s dort jedoch nicht besser ist, dann brauche ich auch nicht wechseln.

[löschfinger]

Eine Geschichte mit Happy End. :D
Wir sind nun auf einen dedicated Server gewechselt, den wir mit einem Partner teilen.

CPU: Core2Duo 2.1GHz
RAM: 2048MB DDR2
