5.10 is LTS. Well, it will be, once it is actually released!

Ah. Small caches? The OpenWRT guys make valid complaints that the code
hot path of the network stack is getting too big to fit in the cache
of small systems. So there is a lot of cache misses and performance is
not good. If i remember correctly, just having netfilter in the build
is bad, even if it is not used.
