Thanks for the v2, I now see the promised perf improvements when running
some quick tests with testpmd. Some quick numbers below, summary version is
that for testpmd with default mempool size startup/exit time drops from
1.7s to 1.4s, and when I increase mempool size to 4M mbufs, time drops
from 7.6s to 3.9s.
/Bruce
cmd: "time echo "quit" | sudo ./build/app/dpdk-testpmd -c F --no-pci -- -i"
Baseline (no patches) - 1.7 sec
Baseline (with patches) - 1.7 sec
Huge-unlink=never - 1.4 sec
Adding --total-num-mbufs=4096000
Baseline (with patches) - 7.6 sec
Huge-unlink=never - 3.9 sec
