How to optimize/tweak Console mode to shorten initialisation?

I defined a Test Suite that runs unattended every 5 min.
The test itself takes only 10 secs to complete though the initialization takes 70+ sec.

  • Is there a way to reduce the time to initialize?
  • is it possible to start a Test Suite on a Console that was init by a previous run?

I’m using KS 6.3.3 on an AWS t2.large instance (CentOS Linux release 7.6.1810)

AWS t2.large:

vCPU = 2
CPU Credits / hour = 36
Mem (GiB) = 8
