Gtmetrix and Pagespeed degraded with Cookie law

Hi Team,

Without EU Cookie Law, our website display an A 91% with GTMetrix and 90% with Google Pagespeed
By adding your plugin, i got D (69%) with GTmetrix and 41% with Pagespeed

I can reproduce the problem by just activating/deactivating your plugin.

Is there any fix on this ?
For your record, i’m using WP Rocket cache and don’t want to change anything in the cache setup due to very fine tuned configuration.

Any help would be greatly appreciated…
Thanks in advance.
Philippe
