I'm not using sysctl, just loading module.

poudriere is for testing ports and it uses jails to build stuff.
It have restrict access to net to fetch distfiles (not the case as
distfile is present on disk)

bonnie++ is a disk benchmark

The previous test [2] was obtained by loading tcp_rack

Now I will post results for test [3] by loading (only) tcphpts module.

[3] kldload tcphpts:

Summary:

- I can't remember better tests to do as I can feel the entire OS is
being slow, without errors, just slow.
- Approx. results as test [2]
