Maksim,
The graphs were not attached. Perhaps the list stripped them. Could
you post them on the web instead?
Thanks,
Eric

hello,
i would like to submit the attached bioq patch for review and
comments. this is proof of concept. it helps with smoothing disk read
service times and arrear to eliminates outliers. please see attached
pictures (about a week worth of data)
- c034 "control" unmodified system
- c044 patched system
graphs show max/avg disk read service times for both systems across 36
spinning drives. both systems are relatively busy serving production
traffic (about 10 Gbps at peak). grey shaded areas on the graphs
represent time when systems are refreshing their content, i.e. disks
are both reading and writing at the same time.
thanks,
max
