Hello Henrik,

Thank you for reaching out and I am happy to help!
This is a public forum so I would advise you to reach out to us directly via the W3 Total Cache plugin, in the Dashboard, Performance>Support>Billing, and provide the information about your subscription and any proof you have that the performance got worse with the activation of our plugin, with some details about the configuration.
You can also reach out via the website contact form here.
The reason for this is that you should not share any sensitive information in the public forum

Thanks!
