scp consumes all CPU when sending data (was Re: 1.7 ssh/rsync consuming all cpu on x64 Vista)

2009-09-04 Thread Jonathan
I just got a new machine with Windows 7 Professional 64bit and did a clean install of cygwin. I still have the same issue as I have on Vista 64 bit where sending data via rsync or scp will max a processor core per process while receiving data only uses a few percent. Is there a chance this

I tried again using 1.7.0-52 (-54 is not working for me) my current uname -a is CYGWIN_NT-6.0-WOW64 SAGER9262 1.7.0(0.212/5/3) 2009-07-24 09:59 i686 Cygwin I simplified things a bit this time by using scp instead of rsync, I still see 100% cpu usage by ssh while sending data. An strace can be

Maybe you want to give the latest Cygwin snapshot from http://cygwin.com/snapshots/ a try. $ uname -a CYGWIN_NT-6.0-WOW64 SAGER9262 1.7.0s(0.210/5/3) 20090628 15:28:41 i686 Cygwin You need to try with the 20090629 snapshot: $ uname -a CYGWIN_NT-5.1 EUSH65 1.7.0s(0.210/5/3) 20090629

I have also tried the rsync transfer from safe mode which makes a BLODA issue highly unlikely and then from a clean 1.7 install after renaming my existing install folder. Rsync and ssh both max out a processor core each for the transfer and it still goes much slower than it should. Should I

Another data point: I only see the high CPU usage when sending, receiving data runs about the expected speed and CPU usage. On 6/28/2009 4:07 PM, Jonathan wrote: I have also tried the rsync transfer from safe mode which makes a BLODA issue highly unlikely and then from a clean 1.7 install
