Sean Busbey updated HBASE-5699:
-------------------------------
Attachment:
HBASE-5699_disabled_and_regular_#workers_vs_MiB_per_s_1x1col_512Bval_wal_count_1,2,4.tiff
Attaching a plot that includes running the same tests with the delegate wals as
DisabledWALProvider, named
"HBASE-5699_disabled_and_regular_#workers_vs_MiB_per_s_1x1col_512Bval_wal_count_1,2,4".
This should show the limit from context switching and such in the test itself.
The DisabledWALProvider doesn't include any of the overhead from the ringbuffer
or sync grouping.
There are very few data points for the new test cases, so I didn't include any
stddev bars. I just used the average for hte whole run. All of them were so
short that they probably didn't have time to get into steady state.
(The disabled wals are at the top, the previous runs with datanode writes are
at the bottom)
