There's two ways to serve gzipped content: In-HTTP by having the
server and browser agree on whether to do it, or just sending gzipped
files.

The former is the most flexible, as the UA's abilities are considered,
and it has to specifically request a gzipped transfer, falling back on
a regular transfer, and it seems the standard say SVG viewers are more
or less required to support gzipped transfers if they use HTTP, so in
general it's a no-loss, probably-gain thing.

I don't use IIS, but a quick google turned up
http://radderz.me.uk/wiki/IIS_GZip_Compression which may be helpful
start.


Generally, sending gzip files is less useful as it counts on the UA
decompressing which nothing really does, but SVG viewers seem to be
the exception to the rule. The standard seems to mention, though not
require it, but I do believe at least all major SVG viewers just load
them. Adobe and Batik do, at least.

Side note:
Adobe's getURL transparently handles gzip compressed  content, meaning
you could also load gzipped svg files from a main svg file. I'm not
sure how much this depends on serving them with the right mime type,
though, ot whether Batik/Corel's implementations of the function do
this too.
