Description Peter Portante 2013-02-06 21:29:50 UTC

Preliminary testing shows that a significant performance benefit can be gained by using one native mount point per object-server worker process.

Raw data for single mount point:
gprfc017.GET.log:total object operation count = 2082
gprfc017.GET.log:throughput =     85.56 objs/sec
gprfc017.GET.log:transfer rate =      0.25 MB/s
gprfc018.GET.log:total object operation count = 2057
gprfc018.GET.log:throughput =     84.53 objs/sec
gprfc018.GET.log:transfer rate =      2.48 MB/s
gprfc019.GET.log:total object operation count = 1568
gprfc019.GET.log:throughput =     64.45 objs/sec
gprfc019.GET.log:transfer rate =     18.88 MB/s
gprfc020.GET.log:total object operation count = 552
gprfc020.GET.log:throughput =     22.70 objs/sec
gprfc020.GET.log:transfer rate =     66.50 MB/s
gprfc021.GET.log:total object operation count = 108
gprfc021.GET.log:throughput =      4.42 objs/sec
gprfc021.GET.log:transfer rate =    129.52 MB/s

Raw data for multiple mount points:
gprfc017.GET.log:total object operation count = 60494
gprfc017.GET.log:throughput =    100.07 objs/sec
gprfc017.GET.log:transfer rate =      0.29 MB/s
gprfc018.GET.log:total object operation count = 59618
gprfc018.GET.log:throughput =     98.62 objs/sec
gprfc018.GET.log:transfer rate =      2.89 MB/s
gprfc019.GET.log:total object operation count = 41732
gprfc019.GET.log:throughput =     69.04 objs/sec
gprfc019.GET.log:transfer rate =     20.23 MB/s
gprfc020.GET.log:total object operation count = 14182
gprfc020.GET.log:throughput =     23.47 objs/sec
gprfc020.GET.log:transfer rate =     68.75 MB/s
gprfc021.GET.log:total object operation count = 2819
gprfc021.GET.log:throughput =      4.66 objs/sec
gprfc021.GET.log:transfer rate =    136.65 MB/s

Comment 2 Kaleb KEITHLEY 2015-10-22 15:46:38 UTC

because of the large number of bugs filed against mainline version\ is ambiguous and about to be removed as a choice.

If you believe this is still a bug, please change the status back to NEW and choose the appropriate, applicable version for it.
