Hi team,

I have faced problem about query performance on Kylin.
I run two instance Kylin(job) and Kylin(query) on two node of my hadoop cluster.

When my cluster have high load, it make kylin query running slow. I think high 
load affect to Hbase so that it make kylin read data from Hbase slower.
But
When my cluster have normal load (average below 10% CPU). I login Kylin and 
test one query, It always slow on first time. When I repeat this query again, I 
see it's faster.
I test with a lot of queries, but it's always slow on 1st try.

I wonder Do Kylin have slower when open connection and faster after that ?

If not So any solution to fix my issue?




Thanks!
