# This function optimizes the usage of memory through blaze, according to the official performance tuning guide:
# https://github.com/samply/blaze/blob/master/docs/tuning-guide.md
# Short summary of the adjustments made:
# - set blaze memory cap to a quarter of the system memory
# - set db block cache size to a quarter of the system memory
# - limit resource count allowed in blaze to 1,25M per 4GB available system memory
