Sounds good, but interestingly, there was some talk about whether reducing the compression would make it quicker, since apparently the data transfer is the slowest part, not the decompression - compressing the data effectively means more data per time period can be read from the cd, since relatively fast cpus can decompress faster than cd drives can read...
There must be a stage at which the drive is fast enough or the cpu slow enough to reverse this, but I don't know where it is, certainly it is not true for hard disks.
