How to speed up loading time of WordPress Dashboard ?

Some times ago i have faced this problem. Whenever i used to login to my WordPress dashboard it was taking long time to load , then i started exploring the root cause of this issue. All these issues that slows down dashboard loading are explained below -

1. Revision History
2. Unnecessarily Created Tables.
3. Unused Plugins

Case No 1 : Revision History

1. When we create any post then after some amount of time WordPress automatically auto saves current version of the post.
2. If by chance we failed to publish post then this feature helps us to recover the older version of the post.
3. This will create redundant posts in the database,increasing database size unnecessarily.
4. One suggestion is that try to clear redundant post revision history.

How to Clear Revision History ?

1. Firstly install Delete-Revision Plugin.
2. Delete Revision plugin delete revision post from Database , let us to drop Redundancy, lose weight !
3. Click on “Yes,I would like to delete them” button so that all redundant posts gets removed.

Cause No 2 : Unnecessarily Created Tables

1. Installing new plugin will create database table (if needed).
2. Creating table is not a problem at all, but after uninstalling plugin table remains in the system.
3. We have to check whether information inside table is useful or not. if not we can drop that table.
4. In order to view list of all table install : WP-DBManager plugin.
5. It will show us all tables in the database.

we can delete database table by selecting appropriate table from
Database ==> Empty/Drop Table

this will drastically decrease load on database engine.It also helps to improve dashboard loading time.

Cause No 3 : Try to Less number of Widgets on Dashboard Screen

try to keep minimum number of widgets on the screen. e.g on the post screen we have number of widgets such as

1. Category
2. Slug
3. Related Post
4. Tags

try to keep them as minimum as possible. If we are not using any widget then its better to hide it.

Cause No 4 : More and More Plugins

1. Don’t install unnecessary plugins .
2. Installing unnecessary plugins will increase list of menus on the sidebar of WordPress dashboard.
