I will suggest installing `recon` on the node and then use

recon:proc_window/3

with reductions in order to figure out what are consuming reductions in the
system. On Linux, also investigate the process with `perf` in order to make
sure it is actually wasting time doing reduction work (beam_emu.c takes up
all the time)
