Re: 6.5.5 much slower than 6.3.6

Here's our timing:

  convert logo: -resize 5000x5000 logo.jpg

  time ImageMagick-6.3.6/convert logo.jpg -quality 75 t2.jpg
  0.709u 0.111s 0:00.82 98.7%     0+0k 0+720io 0pf+0w

  time ImageMagick-6.5.6-4/convert logo.jpg -quality 75 t2.jpg
  0.694u 0.079s 0:00.77 98.7%     0+0k 0+720io 0pf+0w

6.5.6 proves to be slightly faster.  We are not sure why its slow on your
computer.
