this is surely true for dynamic compression, and I
wouldn't use more than level 6 in this case either.

But at that time mod_gzip didn't support maintaining
its own cache of statically precompressed files,
which it does now in 1.3.26.1a.
For these files the maximum compression level would
make sense, as the quota of effective compression
calls is very low for these files.
And the higher the cache hit rate, the more additional
CPU load I am willing to invest for creating the cache
content.
