Is 256K enough?

I’ve got a tough troubleshooting question: Is a single 256K frame relay circuit (256 CIR) adequate enough for 100 Internet users?

A customer is complaining of slow response times getting to our Internet site and in our extranet environment. Upon a site visit, I found getting anywhere on the Internet took 30-45 seconds (yahoo, msnbc, espn, oracle, others…).

Using a 33.6 line from home I’m surfing faster than they are, even within the extranet. However, the customer doesn’t feel their access is inadequate.

Is it warranted to suggest they upgrade their Internet access? Any suggestions?

Thank you for your time!
Dave
