I think that's because SLQB
doesn't pass through big object allocation to page allocator.
netperf UDP-U-1k has less improvement with SLQB.

That sounds like just the page allocator needs to be improved.

some of the heuristics for hot/cold pages are quite outdated
and have been tuned for obsolete machines and also its fast path
is quite long. Unfortunately no code currently.
