All seems rather like road building. Making roads bigger just increases
the amount of cars that use them, hence the scrubbing of the planned A40
widening. Analogy - more cars equals more page views. As far as I can
see, the best way to decide on bandwidth is to constantly monitor
consumption and upgrade accordingly and in anticipation. Along with
this, always gauge bandwidth consumption on spikes, not averages. If a
site's traffic increased the moment bandwidth was increased then that
site's bandwidth must not have been right to begin with.

Also important to note is that connectivity at the other end(client) is
just as important as server bandwidth. If the client has a slow
machine, slow modem or slow provider, they will suffer slow connections
no matter what your connectivity is. We have cable modems in the US
pick up our site at hundreds of K a sec, while someone in the UK could
be trickling through. The browser people use also makes a huge
difference. Netscape and IE are fairly bloated and seem very slow when
compared to a browser like Opera. With Opera, by the time you take your
finger off the mouse the page is loaded. let's hope Geko does the same.


PS Don't rush out and get Opera just yet though, always a caveat, it
doesn't support a number of standards.
