Is that "time to run the extraction algorithm", or "time to read in
image from media and extract"? I think the time to read from the media
would tend to dominate the decompression time.
Either way, could you provide the other time for each algorithm in order
to give a sense of how this might scale to other CPU speeds/media read
If you have very slow media, you probably want to use LZMA. If you have
a very slow CPU and comparatively fast media, LZO might be a good
option... I have heard people asking for *uncompressed* kernels for this
reason, but LZO runs at a significant fraction of memcpy() speed.
