XF 1.4 How can I modify Login Dropdown time and Solve the dropdown Lag?

[DistortedDorian]

Hello there!
I am trying to modify the login dropdown time, I want it to go down a bit slower than it does right now.
First solved but while this login dropdown is going down it lag and it's not my graphics card. Other websites using XenForo have a smooth login dropdown speed, while mine is laggy.
EDIT://This test website is ran off my local computer (localhost)
How would I solve this?

That pretty much solved my first question but I thought changing the speed of this dropdown would solve the lag issue, it's not dropping down as smooth as it should (it's not going down smoothly, it lags while going down)
Any clue why? Also it's not my graphics card, other websites using XenForo have a smooth login dropdown speed, while mine is laggy.

Not sure about it, but I guess it must be something with server.
