As of my tests, loader.conf: tcp_rack_load="YES" loads tcphtps.ko auto:

3    1 0xffffffff81f53000    545e0 tcp_rack.ko
4    2 0xffffffff81fa8000    14588 tcphpts.ko

On aarch64 (rpi4) I didn't get any performance issues in

main-n268730-96ad640178ea (Mar 8)
and
main-n268827-75464941dc17 (Mar 16)

So it seems not related to rack commit e18b97bd63a8: Update to bring
the rack stack with all its fixes in.

Will update amd64 laptop to main-n268827-75464941dc17 (Mar 16) and test it.
