the only difference seems to be the presence of MapCache on the slower system. Could you try removing it ?<div><br></div><div>hth,</div><div>Umberto<span></span><br><br>On Thursday, July 25, 2013, andy wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I'm coming from the linux world, but I have to assume windows would do the same: your os should be caching the snot out of your disk. Hopefully that 6.8 gig of usage is for disk cache. Any way to tell if that's the case? You want all of your ram used as disk cache.<br>
<br>
Is there a way to see how much cpu vs disk is being used? If your cpu usage is high and disk io is low, then you have a huge cache and you don't need more ram.<br>
<br>
If your cpu is low and your disk io is high, then you have a tiny cache, and you could use more ram.<br>
