Witam,
Od jakiegoś czasu przy powiedzmy 40 online, strony strasznie długo się wczytują.
Restart apache, podziała dobrze kilka minut i znowu zaczyna mulić.
Obciązenie procesora jest na poziomie 5%-15% z czego 55% to mysql.
RAM może z 1GB na system i cały serwis.
Łącze jest wykorzystane może w 5-10%...
Zapytania w mysql w 99.99% przypadków wykonywane są w 0.0001-0.0002, niestety czasem zdarza się, że to samo zapytanie trwa 0.5s smile.gif

Ma ktoś pomysły czym może być to spowodowane?
Poniżej apache2.conf (próbowałem dać jako spoiler, ale wyświetla tekst na czarnym tle zamiast go chować... chyba, że rozumienie spoilera zmieniło się przez moją nieobcność)

# 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 and /usr/share/doc/apache2-common/README.Debian.gz about
# Debian specific hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.

# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
#    /etc/apache2/
#    |-- apache2.conf
#    |    `--  ports.conf
#    |-- mods-enabled
#    |    |-- *.load
#    |    `-- *.conf
#    |-- conf.d
#    |    `-- *
#     `-- sites-enabled
#         `-- *
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
#   together by including all remaining configuration files when starting up the
#   web server.
#
#   In order to avoid conflicts with backup files, the Include directive is
#   adapted to ignore files that:
#   - do not begin with a letter or number
#   - contain a character that is neither letter nor number nor _-:.
#   - contain .dpkg
#
#   Yet we strongly suggest that all configuration files either end with a
#   .conf or .load suffix in the file name. The next Debian release will
#   ignore files not ending with .conf (or .load for mods-enabled).
#
# * ports.conf is always included from the main configuration file. It is
#   supposed to determine listening ports for incoming connections, and which
#   of these ports are used for name based virtual hosts.
#
# * Configuration files in the mods-enabled/ and sites-enabled/ directories
#   contain particular configuration snippets which manage modules or virtual
#   host configurations, respectively.
#
#   They are activated by symlinking available configuration files from their
#   respective *-available/ counterparts. These should be managed by using our
#   helpers a2enmod/a2dismod, a2ensite/a2dissite. See
#   their respective man pages for detailed information.
#
# * Configuration files in the conf.d directory are either provided by other
#   packages or may be added by the local administrator. Local additions
#   should start with local- or end with .local.conf to avoid name clashes. All
#   files in conf.d are considered (excluding the exceptions noted above) by
#   the Apache 2 web server.
#
# * The binary is called apache2. Due to the use of environment variables, in
#   the default configuration, apache2 needs to be started/stopped with
#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
#   work with the default configuration.


# Global configuration

#
# 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.
#

#
# 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.
#

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

# 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.
#
# It is also possible to omit any default MIME type and let the
# client's browser guess an appropriate action instead. Typically the
# browser will decide based on the file's extension then. In cases
# where no good assumption can be made, letting the default MIME type
# unset is suggested  instead of forcing the browser to accept
# incorrect  metadata.
#
DefaultType None


#
# 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.

No tak tylko z 5-15%, 55% to powiedzmy 2.8-8% na mysql a gdzie pozostałe 85%?
