Some more thoughts.  I suspect the problem you are encountering can be  
caused by thrashing or a disk failing.  You might want to use top and  
vmstat (whatever its equivalent is for your system) to check for  
excess swapping or disk I/O.  Also check the system log for disk  
errors.  Remapping and retries on drives are quite slow and really  
bottle up the system.
