WP Super Cache

Hello,

I am reading the docs thoroughly and need some clarification. Our site is pretty slow and we’re trying to speed it up. I see in the forums that only a few people are having issues with GD Booster but I don’t see the answer.

GD Docs – Tips and Tricks – It says WP Super Cache now compatible with GD.
GD Docs – Known Issues – It says GD is only compatible with Booster and WP Super Cache is a known issue.

1) Which one is correct? Should we use GD booster or is WP Super Cache the recommendation?

2) I have tried GD Booster and it’s crashing our site. Menus are moving, columns are messed up, etc. I turn off GD Booster and everything is good.

Which should I use?

Thank you in advance for your help. See pictures where it’s confusing us.
