Subject says it all really. Are there any settings in TCPOptimizer that still help improve network/Browser Cache/general speed if you have a Router? Is anyone using both? Any advantages/disadvantages? I have PPPoE DSL so my MTU is set to 1492 in the Router. But looking at the series of patches on the speedguide site, there a lot of settings which you don't set in the Router. Do they still help? Cheers k.
