hi, try the following: - more ram (having 32 mb should improve things, although this depends what the machine is doing apart from routing. routing info isn't swapped, but swapping of other stuff costs performance) - try 3.7, chance is some performance bottlenecks of the systems are improved - try pci nics. - if you find a newer processor for that socket, this could also help. but if you improved the other things, you'll be probably already happy enough.
