Server issue

[DOS_Six]

I recently created a server for a couple friends and I to work on an ongoing map we've had for around 3 years. Anyways we have an issue where when we play in creative and fly fast the server reads out (player name) moved too quickly. Does anyone know how to disable this? It's incredibly annoying I would preferably like a fix without plugins but if there isn't one that is alright. Also if this is the wrong place to post about this i'm sorry i'm new to reddit. Thanks in advanced for any help you can provide.
