Multi-core evaluation in ERDAS Imagine
Paul Beaty has an interesting comparison of the effect of multiple processors when using ERDAS Imagine for processor intensive tasks. In his testing he did two large exports using ECW and JPEG2000. Now I've always found Imagine to be pretty robust and fast; the algorithms appear well written, stable and designed to complete efficiently (although I can't comment on the 2010 version as the disc is currently sitting on my desk unused). Perhaps harking-back to the days when raster processing was costly in computing terms (and so monetarily as well). Anyway, the comparison is stark and clearly 2 and 3 cores are where the biggest gains are made, but if you do this alot then the more cores the merrier!
