Hi Philip!

1. May I ask if the ff settings are dependent or has direct performance correlation with my
ISP servers:

Chimney Offload
Time Stamp

Meaning, if I have different settings than that off my ISP, it may cause connectivity problem

How do we know which settings are appropriate for your ISP? Trial and Error?

2. Windows now has Auto tuning level. It changes the size of the TCP receive window as it sees fit. May I ask then why TCP 123 Time stamp still present?
This setting if I'm correct is also responsible for windows scaling which is automatically adjusted by windows. Looks like redundancy
