Anyone know what makes the dev server run so slow?

First off. Is this a known problem or is it just me? When i run the server in my workspace it is extremely laggy with an average tps of around 10. I am 99.99% sure this isnt a problem with my mod because it is currently being used in a lot of different mod packs including and official FTB pack and i haven't had a single report about lag.

 

So dose anyone have any idea what could cause this?

Ok so there is nothing wrong with the tps it was just out of ram. But the reason i thought that the tps was always low is because for some reason mobs are really laggy. Even when the tps is at 20. This is something i have noticed since i started modding but i only just got around to investigating it.

 

Note to self: Next time i investigate lag. Make sure i don't have two other instances of minecraft running in the background including one very ram hungry mod pack...

All mobs.

Upon further investigation there seems to be some latency between the client and server because i am also noticing block breaking lag. Although i don't know how that is even possible when both the server and the client are running on the same machine...
