Re: how to compare X Ghz processor to Y Ghz processor?

If I'm comparing dedicated Linux hosting offers, is there a rule of

One hosting company suggested I "upgrade" from a machine with an Intel
Celeron 2.8 Ghz to a machine with an Intel Celeron 430 1.8 Ghz. At
first I wondered why the supposedly better one would have a smaller
Ghz number. But I know that an X Ghz processor is not necessarily
faster than a Y Ghz processor just because X > Y. But in that case,
is there a rule for determining which is better? A published list
that lists all processors in order by their speed (assuming a fixed
task like running a busy Web server)?


There are _many_ published benchmarks out there but none are really
much good for anything other than one specific task or for getting
a rough idea of performance.

The only benchmark that counts is _your_ specific application running
under _your_ specific conditions.

Why? Too many variables ( CPU speed, cache, FSB, RAM speed, etc.)
so it is impossible to optimize for all variables at the same time.
"busy web server" could mean many different things. What is keeping it
busy: database access, numeric computations, disk access, etc.

best bet is to take your particular web server/content and try
it out on the different platforms. Failing that figure out your
primary bottleneck now and look at that part of the different machines.

sorry- no easy answers here
