I agree with Chia-Ping Tsai, read-only copy can be changed from LL to array

the suggested changes having any affect on the system performance.Would be very

d the regressions?
Also, I'm worried that the performance regression may be related to an
important bug-fix, where before we may have had fast writes but also risked
incorrect behavior somehow.

Happy Thanksgiving all,
In recent benchmarks I ran in HBASE-18294 I discovered major performance
degradation of master code w.r.t 2-alpha-1 code.I am running write-only
workload (similar to the one reported in HBASE-16417). I am using the same
hardware and same configuration settings (specifical
so that added just one more
variable dealing.

Hi All,
I opened a new Jira https://issues.apache.org/jira/browse/HBASE-18294 to
discuss this question.
Flush decisions are taken at the region level and also at the region server
level - there is the question of when to trigger a flush and then which
region/store to flush.Regions track both the
