Hi Johan!<br><br>MapProxy can perform incredible well, but on todays multi-core server you have to take great care to run multiple MapProxy instances in a non-blocking configuration. <br><br>Starting MapProxy via paster is great for test & development, but for better performance you should take a look at the multiple MapProxy deployment options using FastCGI or WSGI [0].<br>
<br>To better analyze the exception it would be helpful to change the language locale to default using " export LANG='C' " before running paster and repost the exception in English.<br><br><br>cu andreas<br>

<div style="direction: ltr; font-family: Tahoma; color: rgb(0, 0, 0); font-size: 10pt;">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>
