<div dir="ltr">Hi,<br><br>I've made a cache of 30k tiles on disk (200Mo). The network team that I work with want to test tilecache to see how he will behave if our Web site receive a huge amount of user simultaneously. So I send them a list of URL with ramdom BBOX so they can call tilecache in a loop to test it.<br>
<br>They simulate 8 users at the same time and the result is pretty good actually (about 1300 tile /sec.). but to obtain this result, the CPU is only running at 27% of his capacity and even if they increase the number of user, this percentage remain almost the same. So we were wondering how we could use more efficiently the CPU and at the same time, increase even more the performance of the tile serving<br>
<br>Does someone have an explication for this situation?<br>Can we suspect an apache, python or mod_python, windows limitation?<br><br>Here's the technical spec of my server<br><table class="MsoNormalTable" style="margin-left: -0.75pt; width: 249pt; border-collapse: collapse;" border="0" cellpadding="0" cellspacing="0" width="332">
