Well, of course caching would be possible.  But you should pinpoint the
bottleneck first, e.g., by using the profiler as I've described in my
first reply to Stefan.  I can hardly imagine that kpsewhich is so slow
on Mac/Windows.

Here on real operating system (SCNR) and TeXLive 2014

     (benchmark-run 50 (TeX-tree-roots))

takes 5.84 secs.  `TeX-tree-roots' calls `TeX-tree-expand' to expand 4
paths, i.e., the benchmark above performs 200 kpathsea calls in under 6
seconds on my laptop.  Ok, I have an SSD now but had no AUCTeX load
problems on my older system, too.
