Question : best way to find the bottleneck in your internal network?

What is the best way to find the bottleneck in your internal network.

I have  a T1.  in the office but it seems to run a lot slower. My internet home connection is faster..

What specs?  An ADSL line with 6Mbps downstream _will_ be faster than a T1 maxing out at 1.5Mbps.

I have a bonded pair of T1s at work.  Still no match for my fiber connection at home.

Also, your ISP may be running a proxy/cache, which benefits common sites.

You may be trying to compare apples to oranges.
