I saw this too. Since it seems to be SelectOwner that's slow (it was for me too - I have several hundred privileged users on our RT) the thing I did to fix it was to set the appropriate option in RT_SiteConfig to use a text box with the new autocomplete rather than the drop down. It's both much faster to load, and a lot quicker to actually use as well.
