I wasn't trying to imply anything different. It is, however, worth
noting that the Web as a whole is under exponential growth. A single
step-up of 25% is almost immaterial with respect to a load that is
doubling at the rate that we are seeing...
In general,
Servers are going to need to be better designed and the persistant
TCP bugs in kernels are going to need to be fixed. We have already
taken steps on the first part and are working with system providers
on the second. We've also taken steps towards a reducing a large part
of the bandwidth requirements by using persistant caching for the
future releases of our client (Netscape). This should enable servers
to handle *drastically* larger loads. I would hope that these factors
would reduce the accusations of "maliciousness" that other people
have suggested with regards to the client. It is obviously in our
best interests to allow as many people to be served through our clients
and servers. Any action which lowered this number would be crazy on
our part.
