Hi @domialex25 thank you for your review.
We understand that you can get different results from multiple plugins and while some may not need too much tweaking, there are other that have setting that can help you to get even better results, so we would love to take a look and help you with this.
If you would like to give us the opportunity, could you please start a support thread here https://wordpress.org/support/plugin/hummingbird-performance/
Best regards,
