I guess it's because it's doing heavy optimisation of the compression algorithm to get 170MB down to 13MB.

The huffman-type encoding used in highly compressed Mobipocket files gives different amounts of compression depending on choices made in the compression algorithm. Best compression requires large amounts of calculations to find the most compact form.

Luckily, decompression is always quick, since there are no choices to be made in decompresssion.
