No, PHPLib is fast. It is no problem (tested with mySQL and Oracle) to
serv about 50 requests/second. We set the maximum waiting time to 200 ms
for each request. Normal is about 50-100 ms.

The web- and database-server load rises of course to > 1. And of course:
The web- and database-servers are bigger ones. :) On smaller webservers
this could go down to 20 requests/second for example with aceptable
waiting time of 200 ms... but this is also not so bad, cause this
dosn't mean, that 20 request is the maximum -- it could handle more,
but then the user has to wait a little bit more.

The rest of the application slows itself down much more than PHPLIB!
