Hello !

On my local machine (AMD Turion Laptop with 2.1 GHz) I'll get about 
10-20 pages / second for a normal T3 site, and I have xcache installed 
(Which is a quite good PHP accelerator).

When you write "you do not have to care for groups/logins" ... what do 
you mean. If a site has users/groups and different pages are visible for 
different groups, then such a caching extension has to take the current 
usergroup into account.

Also if you server different pages for different browsers the caching 
extension would have to take conditions into account.

So those static-filecache extensions only make sense if you have neither 
users/groups nor conditions - which is not true for almost any site (at 
least concerning the conditions) ...


This is why I wrote about my quickfe extension ... But what I would like 
to have is such a feature group and condition evaluation in a C apache 
or php module.

My laptop mentioned above serves about ~8.000 pages / second (yes. 
eightthousand) instead of 20 lame T3 pages ... I guess you should try an:

ab -c 5 -n 100 http://yourfavoritet3site.org

and have a look what the benchmarks tells, and compare it to some static 
pages being benchmarked ...
