To your and Brock=A1=AFs= questions, my answers are as below.= 

What client are you using to benchmark? You might also be b=
ound by the client performance.

My Answer: we = are using many force testing machines to test the highest TPS on kudu. Our = testing client should have enough ability.=

I'd verify that = the new nodes are assigned tablets? Along with considering an increase the = number of partitions on the table being tested.=

My Answer: Yes, with machines added each time, I created a new tab= le for testing so that tablets can be assigned to new machines. For the par= tition strategy, I am using 2-level partitions: the first level is a range partition by date(I use 3 partitions here, mean= ing 3-days data), and the second level is a hash partition(I use 3, 6, and = 9 respectively for the clusters with 3, 6, and 9 tservers).
