Synology DSM 5.0 on native hardware (DS 713+)
periodically Resource Monitor shows disk utilization of 100% (and peaks of several thousand IOPS for reading)
work with the disk via AFP at the same time ... slow
how to determine who exactly is to blame? CloudStation?BTSync?Glacier? MailStation?
the obvious idea is to go into the Linux console and see who eats the most processor in the top ... it does not always help. I don't know the analogue for viewing exactly the disk loading with splitting by processes. but want to know.
inside there, if anything, is Linux
(uname -a
Linux vrtani 3.2.40 #4493 SMP Thu Aug 21 21:46:06 CST 2014 x86_64 GNU/Linux synology_cedarview_713+)
and there is access to ipkg and, if necessary, you can compile what you need from the sources, the question is what

iotop does not help in this case.
Could not run iotop as some of the requirements are not met:
- Linux >= 2.6.20 with I/O accounting support (CONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING): Not found
- Python >= 2.5 or Python 2.4 with the ctypes module: Found
anyway thanks
I will collect atop means
