It saves space.
About 5 years ago or so, man pages weren't compressed.
(At least I don't recall that they were on RH 4.x) When
the typical hard drive was in the 300-500MB range, the
space gained through compressing man pages was fairly
significant. Given 120+GB drives, it hardly seems relevant
any more, and with today's typical systems sporting 2+ GHz
processors, the cycles to decompress seem about as relevant.
Net: Older machines can more easily fit all the man
pages, even if it does take a second to format them.
