Using InterpolationHigh is very very expensive when resampling
images. For example, it took 1400ms to decode an image on
http://www.crossfitsunnyvale.com/blog/, but it took 2800 ms to do the
resampling Switch to InterpolationLow will result in linear
resampling. It is much faster as the time it tooks is almost
non-noticable [sic] on the trace.
