Tried the same script on lubuntu, just as slow actually. I think ghostscript is the bottleneck.

running the script on Win7, 4.0.0. MXE build I do get the following top items in the profiler summary:

I notice that get took much more relative time on this run than it took in the examples posted in that original thread.

subsequent calls to the script have get down at 0.153 sec, so it must have just been the 'first time' slowdown.
