Description

Lightweight yet safe parametrisation of memory management.

Used as default setting and thus for most tests.

Static Public Attributes
static const size_t	EPOCH_SIZ = 100
	Number of storage slots to fit into one »Epoch«

Public Attributes
const size_t	ACTIVITIES_PER_FRAME = 10
	how many Activity records are typically used to implement a single frame

const double	BOOST_FACTOR = 0.85
	adjust capacity by this factor on Epoch overflow/underflow events

const double	DAMP_THRESHOLD = 0.08
	do not account for (almost) empty Epochs to avoid overshooting regulation

const Duration	DUTY_CYCLE {FSecs(1)}
	typical relaxation time or average pre-roll to deadline

const size_t	INITIAL_STREAMS = 2
	Number of streams with REFERENCE_FPS to expect for normal use.

const size_t	OVERLOAD_LIMIT = 60
	load factor over normal use where to assume saturation and limit throughput

const size_t	REFERENCE_FPS = 25
	frame rate to use as reference point to relate DUTY_CYCLE and default counts

const double	TARGET_FILL = 0.90
	aim at using this fraction of Epoch space on average (slightly below 100%)
