Unfortunately though, the processes that run inside it doesn't seem to get more than 2% CPU. As expected, this works just fine on Linux. >> Is there a CPU time limit equivalent to say 20% or have I >totally misunderstood? > >I'd say it's hard to calculate or estimate absolute CPU time >from relative resource consumption (load).

Basically I run this web app that requires ImageMagick to process photos, but whenever ImageMagick runs, it consumes up to 100% CPU, rendering the actual web app inaccessible (gateway timeout). Thanks! O.D.
