How so? FLAC has a different design objective than some of the commercial 
lossless codecs.
FLAC was intended mostly for "rippers", i.e. people who want to encode a lot of 
CDs, and store them and play them back on computers, so a big emphasis was 
encoding speed.

Other algorithms are designed for max. compression and are thus slower and use 
more CPU but use less space. Others are optimized for minimal CPU use during 
decompression, such as to be workable on low power CPUs in portable devices.

FLAC is but a choice, and not always the best one, from a technical point of 
view, even though it's free.
