I rebuild procps 3.3.17.29-2480 from source and it appears to work, so maybe the stock procps package is incompatibility with the current master branch. (However, I built it against the stock /usr/include, not the current branch...) I first needed to 'make /proc/libprocps.la', and there was an undefined siginfo_t.si_int in ./lib/test_process.c which I just commented-out to get it to build. -- Chris On Tue Aug 31 2021, at 1:23 PM, Chris Roehrig <croehrig AT house DOT org> wrote: > 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. > > > On Tue Aug 31 2021, at 12:53 PM, Chris Roehrig <croehrig AT house DOT org> wrote: > >> 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).
