This thread has rapidly deteriorated into a comparison of web servers, but
let's return to the question at hand: how does the K6 perform? These are
the questions that I would like answers to before I would be willing to go
with the AMD:

- Does the AMD K6 have subtle x86 compatibility problems such as have been
discussed on this list before with the Cyrix chips?

- AMD compares the K6 to the PPro but the chip sits in a P5 socket. Does
this limit its truly functioning as a PPro clone?

- The K6 has a larger cache than the PPro (according to AMD) but it's
accessed at 66 MHz rather than at the chip clock speed as with PPro. How
much of a hit is this?

Once these questions are satisfied, those asked by Jeff above become
important.

If anyone can address any of these questions, it would be much
appreciated.

Thanks,
Karl.
