This tool creates large numbers of TCP connections, each of which will
transmit a fixed amount of data, between client and server hosts. tcpp can
use multiple workers (typically up to the number of hardware cores), and can
use multiple source IPs in order to use an expanded port/IP 4-tuple space to
avoid problems from reusing 4-tuples too quickly. Aggregate bandwidth use
will be reported after a client run.
While by no means a perfect tool, it has proven quite useful in generating
and optimizing TCP stack lock contention by easily generating high-intensity
workloads. It also proves surprisingly good at finding device driver bugs.

quoth the README:
I have been running -current on my laptop since before FreeBSD 2.0 was
released and along the way developed this little trick to making the
task easier.
sysbuild.sh is a way to build a new FreeBSD system on a computer from
a specification, while leaving the current installation intact.
sysbuild.sh assume you have two partitions that can hold your rootfs
and can be booted, and roughly speaking, all it does is build a new
system into the one you don't use, from the one you do use.
A partition named /freebsd is assumed to be part of your layout, and
that is where the sources and ports will be found.
If you know how nanobsd works, you will find a lot of similarity.
o add net80211 support for a tdma vap that is built on top of the
existing adhoc-demo support
o add tdma scheduling of frame transmission to the ath driver; it's
conceivable other devices might be capable of this too in which case
they can make use of the 802.11 protocol additions etc.
o add minor bits to user tools that need to know: ifconfig to setup and
configure, new statistics in athstats, and new debug mask bits
While the architecture can support >2 slots in a TDMA BSS the current
design is intended (and tested) for only 2 slots.

changes:
01 - Enhanced LRO:
LRO feature is extended to support multi-buffer mode. Previously,
Ethernet frames received in contiguous buffers were offloaded.
Now, frames received in multiple non-contiguous buffers can be
offloaded, as well. The driver now supports LRO for jumbo frames.
02 - Locks Optimization:
The driver code was re-organized to limit the use of locks.
Moreover, lock contention was reduced by replacing wait locks
with try locks.
03 - Code Optimization:
The driver code was re-factored to eliminate some memcpy
operations. Fast path loops were optimized.
04 - Tag Creations:
Physical Buffer Tags are now optimized based upon frame size.
For better performance, Physical Memory Maps are now re-used.
05 - Configuration:
Features such as TSO, LRO, and Interrupt Mode can be configured
either at load or at run time. Rx buffer mode (mode 1 or mode 2)
can be configured at load time through kenv.
06 - Driver Statistics:
Run time statistics are enhanced to provide better visibility
into the driver performance.
07 - Bug Fixes:
The driver contains fixes for the problems discovered and
reported since last submission.
08 - MSI support:
Added Message Signaled Interrupt feature which currently uses 1
message.
09 Removed feature:
Rx 3 buffer mode feature has been removed. Driver now supports 1,
2 and 5 buffer modes of which 2 and 5 buffer modes can be used
for header separation.

support machines having multiple independently numbered PCI domains
and don't support reenumeration without ambiguity amongst the
devices as seen by the OS and represented by PCI location strings.
This includes introducing a function pci_find_dbsf(9) which works
like pci_find_bsf(9) but additionally takes a domain number argument
and limiting pci_find_bsf(9) to only search devices in domain 0 (the
only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are
changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order
to no longer report false positives when searching for siblings and
dupe devices in the same domain respectively.
Along with this change the sole host-PCI bridge driver converted to
actually make use of PCI domain support is uninorth(4), the others
continue to use domain 0 only for now and need to be converted as
appropriate later on.
Note that this means that the format of the location strings as used
by pciconf(8) has been changed and that consumers of <sys/pciio.h>
potentially need to be recompiled.
