If your site seems slow, try optimizing the site database to remove gaps in data (also known as overhead). This can help restore speed if the database is at fault, but doesn't fix the scripting that initially created the overhead.
- Go to your Heart Internet control panel and open the Managed WordPress product page.
- Open my phpMyAdmin.
- Below the list of tables, select Check all tables having overhead.
- From the list select Optimize table.
