One of my clients was using #MonsterInsights for their #analytics. I was deactivating #plugins to see which had a negative impact on performance. Most of them didn't do much but when I deactivated Monster Insights I gained 300ms back from total blocking time.

This took me from an 82 to a 98 for mobile performance in #PageSpeedInsights. To make sure, I activated & deactivated 4 times and each time it was the same result!
