I've found you must also copy the matching cygwin-console-helper.exe
for everything to work correctly!

I did a 'git pull' of the latest topic/pipe and rebuilt and I now do indeed get
100MB/s transfers using both rsync and scp (without pipe_byte).
(It turns out last time I forgot 'make install' -- Doh!)
I still get the procps error however.

Thanks, I did some more tests:
scp also shows no improvement with topic/pipe. I tried running
cygsshd with CYGWIN=pipe_byte as well as empty (in the registry
HKLM/SYSTEM/CurrentControlSet/Services/cygsshd/Parameters/Environment/), using
net stop cygsshd + net start cygsshd to restart it. Not sure if that CYGWIN
only applies to cygsshd or to all cygwin tasks.
I get the procps error just running 'procps' command with no args from mintty
(/usr/bin/procps). Looking at the procps-ng source (procps-ng 3.3.17-1 is
what setup_x86_64 reports as my installed package), it appears to be a mmap()
failure.
I'm wondering if I built/installed cygwin1.dll correctly because I don't get
the procps error using the latest stock cygwin1.dll as installed by setup_

I got it to build and tried out the topic/pipe branch (checked out on Monday
around 4:30pm PDT):
1. I didn't see any improvement in my sshd+rsync time, still 3-4 MB/sec.
2. I get the following error from procps: procps:ps/output.c:2195: please
report this bug
(I also get this using the main branch build).
I first updated my cygwin normally using setup-x86_64.exe, then built and
copied only the cygwin1.dll into /bin from the install/bin directory (quitting
all cygwin tasks first).
Thanks for testing.
We're still working on this. (The discussion has moved to the
cygwin-developers mailing list.) I'll let you know when it's stable, and maybe
you can try again.
As to the procps error, can you give details so that someone can try to
reproduce it and debug it?
