[Zope] Zope 2.5.2 vrs 2.7b2 for speed

[BZ]

I went back to check and found a few things:

- someone (me) had put a RAM cache on index_html in the 2.5.2 install 
so I removed it
- the 2.5.2 index_html method called standard header and footers so I 
added that to the 2.7b2
- I could not figure out how to up my ZODB cache in 2.7b2 so I lowered 
the 2.5.2 to 400 items
- Made sure both were debugging off, running FTP, had 20 threads and 
had an interval check of 3000 (tried a few different ones, they didn't 
seem to make much difference)

New results, best of three tries:

Looks like I was smoking crack or something the first time, but I am 
sure that I was seeing the almost direct opposite. Just as an FYI, 
(because everyone likes to compare to apache, which is neither fair not 
relevant since it is usually against a static page) on the same 
machine, on Apache, I am getting around 500 RPS on a very static, 7K 
index.html. Still, with everything that Zope is doing to be 1/5 the 
speed is still damn impressive.

On a whim I tried 2.6.1 with python 2.1.3
