sure that the cache is preseeded. Otherwise it is impossible to say if the
bottleneck is Mapproxy or the WMS behind. In your case I have a feeling it
is the latter.</SPAN></FONT></DIV>

class=139513114-14032011>In my tests with Windows Mapproxy has been performed
rather well. It gives me about 5 times more speed for delivering aerial
orthophotos than my not-so-bad configured MapServer. It also gives
consistent results, the scale of the requests do not have an effect on the
throughput. This is of cource natural because of tiling. Mapproxy also
handles better a big amount of concurrent users (more than 20) than my basic
Mapserver MS4W installation. So even Mapproxy in not perhaps as its best when
used on Windows, it should do better that 10 requests per second. I am sure I
have some exact numbers from tests with jmeter somewhere but I could not find
them right now.</SPAN></FONT></DIV>
