Performance requirements for a site

I have got the following requirement in an RFP

Page Load time	Dashboard, first load, concurrent load peak	Less than 2 seconds.
Page Load time	Critical function, first load, concurrent load peak	Less than 2 seconds.
Page Load time	Reporting function, first load, concurrent load peak	Less than 2 seconds.
Page Load time	Report generation, concurrent load peak	Less than 5 seconds.

The requirements of each page is not clearly defined. So my biggest problem at the moment is, how can I aggree or disaggree with these figures?

Define what each of those means in your response. Or add an assumption list that details the boundaries of how you estimated your work. At least that way you can ask for more time/money if what the client wants is very different from what you estimated.

This can be very difficult if you don't know what each of those elements are comprised of. If the 'Dashboard' has 1 graph that pulls back 100 records, this should generally be no problem. However there are so many other factors, what if 100 records becomes 10,000 over 10 visuals that make up the 'dashboard'. Also is there any definition of guaranteed network throughput to all defined clients? If you have a slow network, 1 client could take 2 minutes to load 10 records on a dashboard and another client over a 100mbps LAN on a corporate network gets it in .01 seconds.

A lot of prerequisites or standards are going to have to be defined in addition to the nature of each requirment to even know if that is possible. And even then without some guarantee in network speed to the client, it can be difficult to ever say those numbers are acceptable.

Most RFPs have a heavily weighted section on project cost/performance and it seems you became the victom of one among.Anyways there is good reason behind disagreeing on this.Your point of disagreeing on REP is that you don't know Page/dashboard Contents which needs to be displayed.So just ask for it.I mean you can also demand for fine grained REP.
