<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Thanks for your comment.<br>
<br>
I will actually test three cases. One directly to the wms, one to preseed and one dynamical(populating the cache).<br>
<br>
the preseed gives nice answers offcourse, the dynamical doesnt.<br>
<br>
You dont have to send me any numbers, thanks anyways!<br>

or the WMS behind. In your case I have a feeling it is the latter.</span></font></div>

<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span 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>

Hey!<br>
<br>
Im performing some performance testing on wms+cache, where mapproxy is included.<br>
<br>
I runn 6000 URLS from a list and use a webstress program to read the list, with 10 request/sec.<br>
<br>
The performance of the test are really low and I think it has to do with this exception.<br>
Anyone nows what this exception means, and/or it can be fixed ?<br>
<br>
<br>
Exception happened during processing of request from<br>
