Good idea. It should not be too complicated to modify "storeUfsWrite"/"storeUfsRead" for example to include some type of compression. However, question is, how effective it would be, as there are many graphic file types, not easily compressable. So it would result in a lot of wasted CPU cycles. A simpler solution might be the usage of a compressing proxy on top of squid. So squid will cache compressed files in all FS available, without any patches.
The simplest way to test that is to compare Squid caching to a regular filesystem (ext3, ext4, reiserfs, XFS) versus to one which compresses its files (ZFS, Brtfs, SquashFS). Keepign in mind the way the FS is compressing (per-inode, versus per-file).
