AutoCAD for Mac

[#1]

Hi to all, I am trying Autocad 2012 and happends a very rare problem.

I have a linux server with samba debian 6.0 stable release with samba (windows) filesystem for data shared.

When i use one file saved in linux (samba) server and try to delete one single line takes 5 seconds to delete, the same file in local filesystem take 0 secods.

I try to find in the forums, because this problem only happends  in MAC, not in windows.

I try diferent mac form one friend (Snow) and happends too...

But all other programs run very well in MAC faster and the network is very faster..

Any body know this problem? and the way to solve it?..

regards!!
