...working with TCP's that do not implement the extensions. The timestamps are used for 2 distinct mechanisms:
RTTM (Round Trip Time Measurement) and PAWS (Protect Against Wrapped Sequences).

Can I safely say that disabling Tcp_timestamps is only a concern on congested networks
esp WAN but on Gigabit LAN, its performance impact is negligible?
