Argh. Then I wasted my time for it because the models you linked to are reason why I created this one for myself.

I don't think you've wasted your time, no. Model looks great!
p.s. your Warfare remake looks absolutely fantastic!

BTW you guys should work on (if you already aren't) getting these models into the Xonotic repo so that mappers can easily use and find them! I suppose it'd also be great if someone collected the best GPL-compatible ones from opengameart and had them put in the repos.

If not the repo, we should at least have some place where these can be collected for easy viewing (someplace easier than browsing a long thread like this one)

And then things could happen like watching a map through 2 or 3 warpzones, which will cause huge fps drops.

If it's iteration you mean, i.e. warpzone through warpzone, then that is not supported (or as far as I know still not supported) in Xonotic. There are no worries that'd impact performance. However it'll look ugly as the 2nd iteration will just be a black square in place of the warpzone. (mappers obviously want to avoid it for this reason)

What however does impact performance (on maps, port-o-launch isn't as much of an issue until everyone shoots their pair of portals around :-P) is if there are several warpzones that you can look through at once. This triggers new renders, one for each warpzone, and THIS slows things down quite a lot...
