I have done everything you suggested to improve speed. I use Smushit, W3TC and I still have a speed of 80. I tried uninstalling and reinstalling, but all my customization remained. How to I remove Iconic One Pro and also remove my previous customizations. Perhaps, this will restore my speed.
I deactivate Avatars and speed went up one point. I then deactivated All share icons…Speed went up to 88. I reactivated Sharing icons and the Speed stayed at 88 on Google Insights and 96 and 98 on GMetrix! Can you tell me my deactivating and reactivated Social Icons increase my speed? Is that a glitch?
