Summary: io throtling based on /proc/loadvg
Product: rsync
Version: 3.1.0
Platform: All
OS/Version: IRIX
Status: NEW
Severity: enhancement
Priority: P5
Component: core
AssignedTo: way...@samba.org
ReportedBy: spa...@yum.pl
QAContact: rsync...@samba.org
Rsync could use system loadavg (/proc/loadavg) measure to throttle disk
operations on both sites. This especially includes file table operations as
those are more costly. Checking loadavg every file is not a good idea, but
checking it every x seconds (when next file accessed) could be ok. If max load
is exceeded operations should freeze for few seconds (possibly another
parameter)
--load-check-interval-min = 5 (seconds)
--max-load = 8
--load-freeze = 10(seconds)
