On a multiplayer server, named Swag-craft, in Creative I was walking, and when I went to run, I had to wait 1 mississippi (second) before my guy actually ran. My connection was fairly well, too. I know it was definitely NOT lag.

What I expected to happen was...:
I would run right away.

What actually happened was...:
The running motion was a second late.

Steps to Reproduce:
1. Go into Creative (Or survival, it might be there too)
2. Start running.
3. You will see that I am right.
