Even while these options are set to 0.5, players can still use /speed 10, which is definatly faster then /speed 5. Tested it, so it seems these limits are not working.

Set the max fly speed, values range from 0.1 to 1.0

max-fly-speed: 0.5

Set the max walk speed, values range from 0.1 to 1.0

max-walk-speed: 0.5

Can you give your startup log (that will provide essx and spigot versions) as well as your permissions file and your essentials config.yml please :) all in pastebins of course.

Sorry for the delayed reply, I had issues with my laptop. Hereby the requests:

Essentials startup log: http://pastebin.com/6BHyh7be
Permissions file: http://pastebin.com/ASpCFaBf
Essentials config: http://pastebin.com/Fjj77gGe

Isn't those limits more to hinder the vanilla speed, not to stop the speed you can get by essential commands?

It would be better if it would deny the use of /speed 6 or higher. When testing 5 against 10, you can see that this setting does not work as expected.

Closing in favour of #2148.
