Tips for improving your connection:
Lagspikes are often caused if you use a wifi connection; lan is way more reliable and will surely take away any lag caused by your router
Plausible causes for bad connection:
The Emps server is hosted from western europe: if you are more than 5000km away from west-europe you are sure to have a base delay of around 0.2s or more.
Your ISP may be causing issues. Make sure you are on a 100mbps line or more to play online games properly (viewed in the properties of your connection) and confirm with your ISP that you are getting 100mbps if your subscription says so.
Your lag isn't actually lag, but your game is running slow either way: You are using too high graphic settings. View in the graphic settings tab how much fps you really have and make sure that it is above 25-30 at all times for a smooth performance.
If you are still having issues, please
read this topic first and post a bug report about it.
Complaining about it and accusing Emps-World without actually identifying it will not accomplish a thing.
