1) This is a 7 Day demo trial version.
2) Using ICMP Echo Request with variable buffer sizes it calculates your best MTU (i.e. the MTU that might give you the least fragmentation)
3) It has some sort of algorythm that will calculate your current bandwidth. I would not trust this in determining your real bandwidth as it relies on math calculations and the ICMP protocol.
4) It also tells you your MaxMTU.
5) It will calculate your RWIN based of its bandwidth algorythm.
Overall this is a clean utilitly for the tweaker who want's not to fiddle with anything in his registry he can just load this up and set optimize and it will do it for him.
Problems:
I couldn't ping really much of anything. I tried stuff I could clearly ping in cmd.exe and it wouldn't take.
Since I use a UGate router with the new firmware it doesn't set my MTU/MSS accordingly because it uses ICMP. My REAL MTU is 1476 because of the UGate that limits it.
The speedguide.net tweak tester tells me all the real info
