Here's what Google does for the 'KmlLayer' feature of their v3 API : the KML
url is sent to Google's servers, KML source is retrieved by them, and
rendered into image tiles there. The client API only requests a dozen or so
tiles, all the intensive processing is done at Google's powerful servers and
none at the client side.
(As a bonus this process gets around same-domain XML restrictions as well.)
To get the same performance, you need some server-side service to remotely
process and render your KML as, say, a WMS. I think you may be able to do
that with Mapserver?
