Lower latency going through FreeBSD than directly to router

post #1 of 2
Thread Starter 
I have a very weird situation going on that I would like to clear up. I have three computers at the moment, a FreeBSD 9 64-bit server, a MacBook Pro, and a Windows 8 machine. I have the FreeBSD server set up so that it shares the internet connection with the rest of the Ethernet ports on the server, and while using FreeBSD as my gateway I find it that I usually get 24-25ms in latency pinging to google servers (google.com), but when I connect my MacBook or the Windows machine directly to the DSL router, I average 29-30ms. Both the router and the FreeBSD machine have DNS servers pointing to Google's if that matters.

Can anyone guess whats going on? I thought it would have higher latency going through FreeBSD since the packets have to travel through more hardware.

Which specific address? Something like 'google.com' usually gives you a different server each time you query the record (you'll get the same record if the association is still in cache).

Also, not sure why 4-5 ms over the course of what is likely around 15 hops is of any concern.

If you want more specific testing, just test your first WAN hop. Run a traceroute to something like 8.8.8.8 and ping against the first IP that isn't your router. Then you can modify a configuration and see exactly if it is that specific hardware or not.
