We are using in-memory. I see most latency in ODE service..I don't have a way to determine
CPU utilization by service unit. 

I added instrumentation in the code to find time spent in each service unit..time spent in
all but ODE -SU is less than 40 ms..but ODE-SU is around 2000 ms.

What test case did you run on your laptop? Also, do you have any optimization tips?

How do you determine most of the CPU time is spent in Ode?   In what parts

On my dual-core laptop I easily get 100+ TPS with in-memory processes, so my
guess is you have a bottleneck somewhere else.   The hard part, of course,
it to find where!
