Dock hide-show lag

I ave my dock set to auto hide to save space on my macbook desktop.

One thing Im finding annoying is that every time i hover over my dock to get it to display, it lags and is not as fast as I would like it to be.

Do you find this?
Is there any way to make it more responsive?

I'm guessing you have rebooted?

No, i havent tried that. does it make a difference to the dock response time?
