Seiten laden erst nach einiger Zeit

Hallo Leute,

ich habe vor einigen Tagen meinen neuen Server bezogen.
Allerdings habe ich da das gleich Problem wie bei dem Vorgänger am Anfang, die Webseiten laden mit verzögerung.
Ich hab dummerweise die Configs des alten Systems nicht mehr weshalb ich nicht schauen kann, was es war.

Also, rufe ich eine Domain auf, die auf dem Server liegt, passiert ersteinmal garnichts. Nach 4-5 Sekunden lädt dann die Seite.

Weiß jemand von euch, in welcher Config ich Einstellungen vornehmen muss, um dieses Problem zu umgehen?

Viele Grüße,
Timo
 
*Kristallkugel zerdeppert* (Wie bereits oefter beanstandet... Importware halt :( )

Welcher Webserver ist auf dem Root? (ja es gibt so einige...)
Ich tippe spontan auf den 2. Indianer, dieser laesst sich mit dem Super-Perforator Song wieder gluecklich machen.

Ehrlich ein paar Details waeren wirklich nett ;)

Einige Moeglichkeiten waere ein Bottleneck bei VPS/RPS im Disk-IO, nicht genug SpareChilds, alle Fastcgi's tot, ....
Hier findest du Anregungen und Konfigurations-Snippets desbezueglich
=> http://huschi.net/category10-web-server.html
 
Achherrje stimmt :)

Also, System ist Debian 5, Webserver ist Apache2.


Hab nun

Code:
KeepAlive On
KeepAliveTimeout 2
MaxKeepAliveRequests 10
HostNameLookups off

in die apache2.conf eingefügt und reloaded/restartet.
Es dauert noch genau so lange...
 
KeepAlive aendert nichts am ersten Aufruf welcher bei dir das Problem zu sein scheint.
Hast du die anderen Fragen bez max. Anzahl an Worker / Forks und Fastcgi verfolgt?
(Letzteres natuerlich nur sofern PHP nicht als mod_php werkelt)
 
Ja, aber daran liegt es nicht.
Das gleich Problem hatttte ich beim letzten Server auch, komme aber nicht mehr drauf, was es war :(
 
Hallo,

ich stelle hier nochmal meine komplette apache2.conf rein.
Vielleicht schaut jemand mal drüber.
Es sind immer ca. 4-11 Sekunden, die die Seiten brauchen, wenn sie laden sollen.
Ihr könnte es ja mal selbst testen: http://www.timo-brandt.de

Bei anderen Seiten, wie Wikipedia etc. laden die Seiten sofort wenn ich sie aufrufe.

Code:
#
# 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 "/var/log/apache2/foo.log"
# with ServerRoot set to "" will be interpreted by the
# server as "//var/log/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-2.1/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.
#
#<IfModule !mpm_winnt.c>
#<IfModule !mpm_netware.c>
LockFile /var/lock/apache2/accept.lock
#</IfModule>
#</IfModule>

#
# 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 Off

#
# 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 10

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 2

#
# DefaultType is the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value.  If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
DefaultType text/plain


#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off

# 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

#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
#
LogLevel warn

# Include module configuration:
Include /etc/apache2/mods-enabled/*.load
Include /etc/apache2/mods-enabled/*.conf

# Include all the user configurations:

# Include ports listing

#
# The following directives define some format nicknames for use with
# a CustomLog directive (see below).
# If you are behind a reverse proxy, you might want to change %h into %{X-Forwarded-For}i
#
LogFormat "%v:%p %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

CustomLog /var/log/apache2/other_vhosts_access.log vhost_combined

#
# Customizable error responses come in three flavors:
# 1) plain text 2) local redirects 3) external redirects
#
# Some examples:
#ErrorDocument 500 "The server made a boo boo."
#ErrorDocument 404 /missing.html
#ErrorDocument 404 "/cgi-bin/missing_handler.pl"
#ErrorDocument 402 http://www.example.com/subscription_info.html
#

#
# Putting this all together, we can internationalize error responses.
#
# We use Alias to redirect any /error/HTTP_<error>.html.var response to
# our collection of by-error message multi-language collections.  We use 
# includes to substitute the appropriate text.
#
# You can modify the messages' appearance without changing any of the
# default HTTP_<error>.html.var files by adding the line:
#
#   Alias /error/include/ "/your/include/path/"
#
# which allows you to create your own set of files by starting with the
# /usr/share/apache2/error/include/ files and copying them to /your/include/path/, 
# even on a per-VirtualHost basis.  The default include files will display
# your Apache version number and your ServerAdmin email address regardless
# of the setting of ServerSignature.
#
# The internationalized error documents require mod_alias, mod_include
# and mod_negotiation.  To activate them, uncomment the following 30 lines.

#    Alias /error/ "/usr/share/apache2/error/"
#
#    <Directory "/usr/share/apache2/error">

Ich denke, das Problem ist hier an anderer Stelle vergraben, nämlich der Webseite.

Wenn du Webseiteninhalte von externen Seiten laden lässt, z.B. Bilder extern verlinkst oder Partnerprogramme nutzt, die externe Webinhalte über einen Iframe oder der gleichen includen, läd deine eigene Webseite nur so schnell, wie auch die Webseite dessen Inhalte du includest.
 
Hallo,

nein, ich denke nicht.
timo-brandt.de fordert von keiner anderen Seite Informationen an, es werden auch keine Frames verwendet. Und wie gesagt, das gleiche Problem hattre ich schonmal, aber ich weiß nicht mehr,was es war....
 
Eins ist defintiv; es liegt nicht am Apache-Core sondern an Modulen oder vHost-spezifischen Konfigurationen.

20 Anfragen auf www.timo-brandt.de/ dauerten 56.43 Sekunden (typo3 error page) *
20 Anfragen auf asda.timo-brandt.de/ dauerten 01.18 Sekunden. (Plesk default page) *

Ich nehme somit an dass es an PHP oder MySQL liegt (alle Anfragen setzen afaics eine Datenbankverbindung voraus da ein CMS werkelt)
Somit waeren wir wieder an der Initialfrage ob nicht der DIsk-IO das Problem ist...
(Bei einem vServer kann es auch sein dass deine 'RAM' sich im SWAP befindet...)

* Getestet mit 'ab -n 20 -c 1 WEBSEITE' von einem Proplay vServer in FFM.
