Thanks for your reply. So in order to fix this what do i need to do ?

[Bad Lag When Cutting Trees ONLY!]

So i set up my server a few hours a go. I went to chop a tree down with an axe and the block re-appeared then suddenly the whole tree came down.

I dont think its my computer but i will post specs anyways:-

8GB Ram

Quad Core 965BE @ 3.8GHZ

7870 2GB

2TB HDD

The Server is set up to run a maximum of 4GB of Ram.

Please help..... :)
