Links on galleries: redirect or direct ?

[Jab]

The tour links, I mean..

Which would be best:

1. Use subdomain redirects (such as http://xxxsitename.shortdomain.com/) to conceal the refcodes BUT users have to wait a little longer to see the page (mainly due to the extra dns lookup).

2. Stick to the faster direct links, although some users shun affiliate links.

Would you trade a little time off your pageloads for clean links ? Is it worth it ?

Thanks !
