Not all signals are ignored. The TERM and INT signals correctly
terminate the process. I would like to send STOP and CONT to throttle
the CPU usage of a rsync process. I want to avoid spawning a bash
process to start rsync because it is started from a Windows process. If
I invoke a shell process to invoke rsync, it will be difficult to get
the windows process id so I can translate it to a cygwin process id and
send it a signal.
Any suggestions?
Use --bwlimit=KBPS. This should indirectly throttle cpu usage. This
won't have an impact on the initial cpu-usage if you specify -c to force
check-summing of all files.
