GarbageCollection enum
Values
- stop → const GarbageCollection
-
Stops the garbage collector.
- restart → const GarbageCollection
-
Restarts the garbage collector.
- collect → const GarbageCollection
-
Performs a full garbage-collection cycle.
- count → const GarbageCollection
-
Current amount of memory (in Kbytes) in use by Lua.
- countBytes → const GarbageCollection
-
Remainder of dividing the current amount of bytes of memory in use by Lua by 1024.
- isRunning → const GarbageCollection
-
Return 1 if GC is active (not stopped); note that GC may not be actively collecting even if it's running
- step → const GarbageCollection
-
Perform an explicit GC step, with the step size specified in KB. Garbage collection is handled by 'assists' that perform some amount of GC work matching pace of allocation explicit GC steps allow to perform some amount of work at custom points to offset the need for GC assists note that GC might also be paused for some duration (until bytes allocated meet the threshold) if an explicit step is performed during this pause, it will trigger the start of the next collection cycle
- setGoal → const GarbageCollection
-
tune GC parameters G (goal), S (step multiplier) and step size (usually best left ignored)
garbage collection is incremental and tries to maintain the heap size to balance memory and performance overhead this overhead is determined by G (goal) which is the ratio between total heap size and the amount of live data in it G is specified in percentages; by default G=200% which means that the heap is allowed to grow to ~2x the size of live data.
collector tries to collect S% of allocated bytes by interrupting the application after step size bytes were allocated. when S is too small, collector may not be able to catch up and the effective goal that can be reached will be larger. S is specified in percentages; by default S=200% which means that collector will run at ~2x the pace of allocations.
it is recommended to set S in the interval
100 / (G - 100), 100 + 100 / (G - 100))
with a minimum value of 150%; for example:- for G=200%, S should be in the interval
150%, 200%
- for G=150%, S should be in the interval
200%, 300%
- for G=125%, S should be in the interval
400%, 500%
- for G=200%, S should be in the interval
- setStepMul → const GarbageCollection
- setStepSize → const GarbageCollection
