Research direction
Start by inspecting lualib/resty/lrucache.lua at line 158 and trace the calls from kong/router.lua lines 958 and 1221 through kong/runloop/handler.lua:699 and kong/init.lua:705. Reproduce the reported worker CPU usage if possible and determine whether the lrucache path accounts for it; done requires a confirmed cause and a focused regression test or documented non-bug finding.
