SubjectRe: New Feature Idea: Compress swap file

I'de like to add to my own post:

This might actually increase performance while swapping (as long as there
is CPU to spare) because it can actually take less time to read compressed
data off the drive and decompress it then it would take to just read the
data (because the decompression is several times faster then the HDDs
currently available)..
