[Ur] little benchmark on querying a table only

yes. I don't see why this would make the test totally useless?
Caching may take place. Usually I run the same test multiple times
eg PHP - Ur - PHP - Ur
If the first and second run differ significantly I hit something you
described. But this time I didn't.
 
I reran the test using 10,000 rows:
  urweb:  24.816 tota
  php:    0.502 total

This time I even used 

$s .= "..."
instead of echo "..."; in PHP.
its still faster.
Adding ob_start(); (output caching) doesn't make a big difference.

Of course you don't serve 10,000 rows usually.

I also retried with one row only. Then the difference gets smaller.

So the speed difference occurs somewhere from querying to concatenating
the output.
