We've got a patch which enables lru_cache for use_reduce, vercmp, and catpkgsplit: https://archives.gentoo.org/gentoo-portage-dev/message/a4db905a64e3c1f6d88c4876e8291a65

Cache sizes were selected to minimize memory use increase, while still providing about the same speedup compared to a cache with unbounded size. "emerge -uDvpU --with-bdeps=y @world" runtime decreases from 44.32s -> 29.94s -- a 48% speedup, while the maximum value of the RES column in htop increases from 280 MB -> 290 MB. "emerge -ep @world" time slightly decreases from 18.77s -> 17.93, while max observed RES value actually decreases from 228 MB -> 214 MB (similar values observed across a few before/after runs).
