Many of the questions below are answered from the documentation
in proxyTools:
1) most programs can be run with a 'help' option, like this:
perl statProxy.pl -h
2) most programs have documentation embedded in the source code.
One way to get that is this:
perldoc statProxy.pl
3) double-click 'readme.html' in the proxyTools directory to see
the web page docs for all the tools.

Akk! That's still there? You must have an old version of perl, I
think. I had some code to get rid of that, but recently I've
removed it.
It's not a proxyTools problem, and it causes no harm.

Your best option is to make a smaller file and measure that.
To be honest, I haven't used a dialup for these tests for a long
time now.
On a capped 40KB/sec line, SP will do all 20 tests on each proxy
in under a second. There's a 20 second timeout after cessation of
activity though, so if you test just one proxy, it will take (on
average) 21 secs. The time per proxy is decreased if you
are running less tests per proxy. You are running only one, but
test 13 is slower than most, and depends mainly on the speed of
the proxy you're testing. In fact, it looks like it's taking over
1/2 sec per proxy on my system (not a very fast system)!
There's also a Windows limitation to consider. Windows gets weird
whenever you try to open too many simultaneous socket connections,
so SP waits for them to die away at times. That's dependent on
your type of Windows. Mine is a server, so there may be an
advantage there.
I remember adding an option for low bandwidth connections:
perl statProxy.pl -t 13 -m -l proxyList.txt
but IIRC it only helps with the large downloads involved in
test 0 (the basic proxy function test). If I were you, I would
like to see test 0 results anyway - change the test parameter to
0:13. That will give you a way to get rid of dead proxies before
spending time on the slower anon tests. Even in Freerk's excellent
lists about 30% will be dead by the time you test them.
I should have mentioned that a personal firewall might interfere
with these tests. Test 13 involves getting the proxy under test
to connect back to you as if you are a web site. I don't think
that would increase the overall time though, since all the
tests are done in parallel. Err on second thought it might if your
Windows version is old, or limited, and the number of open sockets
gets high. See comment below.

It should tell you where the results have been copied.
Be careful how you abort.
One ctrl-c will just screen print the results so far and continue
the tests, 2 ctrl-c's (before the end of the above screen print)
will cause abort with file write, 3 or more (before the end of the
screen print) will abort with no screen print (if they were
quick enough) and no file write.
The ctrl-c counter is reset at the end of that screen print.
On a very slow computer, three ctrl-c's are more likely to cause
an abort without writing the file (or even displaying on the
screen) as you can see.

Hmm .. it probably means you have a slow computer and it was too
busy in the o/s network stack to listen to signals back in the perl
code. Try that '-m' option.

See above.

Yes. No.

The '-' says to write them to the screen. Put a filename there if
you want the results in a file. Use tee.pl if you want both at the same
time.

SP doesn't do it.
Unix or Cygwin systems have a sort tool. No doubt there are some
for MS Windows too.
I do it by using my trusty text editor (TextPad) on the result
file. The latencies are all starting in the same column, so
they're easy to sort. Note that you *must* do test 0 to get the speed.
The real answer lies in the 'todo' list for sortProxy.pl, but I never
got a round tuit.
