If you are using the WP Toolkit extension, it detects new
installations performed through the Application Catalog (or Application
Vault) and integrates them with WP Toolkit. For this reason,
installation of WordPress on a site takes up to 20 seconds. If you want
to avoid this, you can switch off automatic detection of new
installations by the WP Toolkit.
To do this, add the following lines to the
panel.ini
file:
[ext-wp-toolkit]
autoAttachApsInstances = off
