Quick benchmark of cache

[Joshua Eichorn <jeichorn JoshuaEichorn com>]

               Time    Requests Per Second    Transfer Rate
Just Apache    5.072        985.80                               8239.16 
kb/s
Cache          19.652      254.43                               2097.97 kb/s
No Cache       72.438      69.02                                 567.80 kb/s

As you can see the cache is a huge speed advantage over generating cache 
page, even though this page is pretty simple just a
echo str_repeat("<h1>Testing</h1>",500);

The reason for this is of course the overhead of doing output buffering, 
and the fact that each page is being written to the cache
while not bad my pIII 700 mhz with 256mb of ram can't fill a T1 without 
the cache

Well thats a basic benchmark, if the cache isn't fast enough yet i'll 
put more work into it, otherwise i'll just leave it as it is and work on 
adding
other features.

The first time is the display of a cached test page, the second time is 
the display of the copy through just apache, the third run is the 
generated page with the cache turned off.
