Lansweeper has become slow

[ifm]

For some time now our Lansweeper (4.2.0.77) has been very slow.
Is there anything I can do to optimize the speed (not with hardware)?

Lansweeper SQL database is 3,99 GB

Problem resolved through email. The Lansweeper database was full.

Could you contact us at support@lansweeper.com and provide us with a screenshot of your web console landing page. You can access your landing page by clicking on the Lansweeper logo in the top left corner of the web console. Please show us the whole page.

Sorry, I should have been more specific.
When i search for a computer and waiting for results to popup.

Could you clarify where you are experiencing performance issues. In scanning your machines? In viewing reports within the web console?
