Unified Performance Tool (or uperf for short) is a network
performance tool that supports modelling and replay of various
networking patterns. It represents a new kind of benchmarking tool
(like filebench) where instead of running a fixed benchmark or
workload, a description (or model) of the workload is provided and
the tool generates the load according to the model. By distilling
the benchmark or workload into a model, you can now do various
things like change the scale of the workload, change different
parameters, change protocols, etc and analyse the effect of these
changes on your model.
Some of the questions you could answer using uperf are:
* Bandwidth and latency (unidirectional and bi-directional) with different
protocols like TCP, UDP, SCTP, SSL
* Connection setup and teardown scalability for different protocols
* Effect of noise on ongoing network connections
* Does it matter if I use processes instead of threads to do network
communication?
* What is the L2 cache miss rate for connection setup?
* Is sendfilev(3EXT) (with one file) equivalent to sendfilev(3EXT)?
* Understand TCP, UDP, SCTP, SSL performance under a variety of conditions
* Test various TCP Congestion control algorithms
===> The following configuration options are available for uperf-1.0.8,1:
DOCS=on: Build and/or install documentation
===> Use 'make config' to modify these settings
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Update to the latest commit
While here:
- Use DISTVERSION as suggested by the Porter's Handbook instead of
GH_TAGNAME.
- Clean up the port a little bit.
