Each tabletserver is ingesting 90M entries/second? That sounds pretty 
darn good to me for a 3GB heap.

All Accumulo configuration should be consistent across *all* nodes 
running Accumulo processes.

I don't believe you have shared the characteristics of your hardware yet 
either. What are the available resources? How much memory, CPU, network, 
and I/O (number and types of disks)?

I also am not comprehending what you are asking with this question: "Is 
my cluster does not change the scale of the cluster, no way to do to 
upgrade it"

Let's approach this from a different angle: what rates are you 
*expecting* to see and what gives you this expectation?
