I would be concerned about the swap. You have 500MB of swap used. In my 
experience as soon as the system starts swapping performance falls off 
dramatically. Is it a 64bit system? With only 2 GB memory it could be a 
32 bit system. Perhaps you moved from a 32 bit operating system to a 64 
bit one and that may require more memory.
