Support » Networking WordPress » Slow Mutlisite Performance

  • Dear all,

    We have a multisite WordPress network that is based on SubFolders, and we’ve had some issues regarding the overall performance of the network.

    The problem is that all the network sites have a very slow performance when they login, edit post, edit page, view themes, view plugins or any other activities.

    We’ve tried to follow up the problem and we temporarily solved it by switching all sites to this theme:
    and by also disabling functions.php on this theme. After this all the sites are working fast with no lag. But we need to enable users to choose themes and use them.

    Here’s our htaccess file configuration:

    # BEGIN WordPress
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    # uploaded files
    RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]
    # add a trailing slash to /wp-admin
    RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]
    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^ - [L]
    RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
    RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
    RewriteRule . index.php [L]
    # END WordPress
    AddType application/octet-stream .rar
    <IfModule mod_security.c>
    <Files async-upload.php>
    SecFilterEngine Off
    SecFilterScanPOST Off

    Our base URL is , could anyone help us resolve this issue.

    Best Regards.

    What kind of server are you on?

    Our server is:
    Microsoft Windows Server 2003 R2

    Can you help please with my problem?

    Well the short version of your problem is this: The other themes you were using aren’t friendly with Multisite.

    The longer version is this: Some themes and plugins use more memory than others, so you may need to invest in better hardware. This is especially true of Windows, which is the least supported hardware in the WP world.
