building lag

hi
i have a problem.
when i build or edit something, there's seems to be sort of a lag or a time jump.
i'll try to explain:
suppose i rotate an object by 90 degrees.
it would appear to be rotated for 2-3 seconds, and then jump back to it's previous position, or somewhere in the middle.
same goes for moving - if i'll move an object from point a to b, it will stay in point b for a few seconds, and wil then jump into point c, somewhere between a and b.
is that a bandwidth problem or something i can sort out by fine tunning my options?
thanks

Usually caused by packet loss - at least, I get this effect badly when I have a poor (lossy) connection, and don't get it at all when the connection is running well.

You could try lowering your bandwidth setting - it should be LESS than your actual line bandwidth.
