The performance point being made clear by Thomas I think I should mention a couple of (mostly in functionality) advantages that the WxS wrappers might have against cgi/fastcgi:<div><br><div>1. it is easy to extend the wrapper to add accounting, logging, caching. True, accounting and logging can also be accomplished simply by processing the web server log files but that requires extra software and might not be easy to impement in complex situations (think a cached request costs x and a non-cached y)</div>
</div><div><br></div><div>2. request preprocessing: filtering layers, redirecting</div><div><br></div><div>3. image/response prostprocessing: caching, assembling, watermarking,...</div><div><br></div><div>Umberto</div><div>

I have tested cgi against python mapscript (with mod_python) and the performance improvement, as expected, is massive.<div><div><div class="gmail_extra"><br><br><div class="gmail_quote">On Wed, Nov 7, 2012 at 8:53 AM, Spirifer <span dir="ltr"><<a href="mailto:ready945@gmail.com" target="_blank">ready945@gmail.com</a>></span> wrote:<br>

<br>
I would to use MapServer to create WMS/WFS services.<br>
<br>
I think to compare 2 systems to produce services:<br>
1) Apache + MapServer CGI + static mapfile (.map)<br>
2) Apache + MapScript PHP + map configuration in cache<br>
<br>
Somebody has tested the performance between the mapfile and MapScript ?<br>
<br>
Thanks.<br>
