On a small page you might see 15KB shrink to 4KB, so a 75% reduction. On some pages we'd see even more impressive gains, up to 98%, but that usually indicated we were putting too much stuff into ViewState and should fix that before applying compression. What's great about ViewState compression, as opposed to IIS page-level compression, is that the ViewState is compressed in both directions---when the user downloads the page and when they post back. Having a user submit a few hundred KB back to the server on each page request can really slow things down because typically home internet connections are optimized for downloads rather than uploads.

What where the file sizes (in both the compressed and uncompressed versions) after gzip ?
