Results on both machines over per-connection emulated links: seven grace delay settings with a fifth client CPU; the promising ones over three link qualities (100 Mbit/s 2 ms 0.1%, 20 Mbit/s 5 ms 0.5%, 5 Mbit/s 25 ms 1%); copying against splice() with and without grace delay, the CONNECT mix included; and the slow link with waits matched to its rate (10 and 20 ms). Grace delay saves 35-46% of 3proxy's CPU per gigabyte on streams at 20 Mbit/s and 21-29% at 5 Mbit/s with a 10 ms wait, does nothing on fast links, and costs CPU with waits too short for the rate or once the CPU is exhausted. Over these links splice() and copying cost about the same in the mix scenarios. A caveat says that every scenario but the mix ones is synthetic.
