Greetings!
Variable Type Default Description
GCL_MEM_MULTIPLE float 1.0 fraction of runtime ram to consider
GCL_GC_PAGE_THRESH float 0.5 only GC past this heapsize fraction of
working mem
GCL_GC_ALLOC_MIN float 0.05 minimum alloc fraction between GCs
GCL_GC_PAGE_MAX float 0.75 GC at minimum alloc past this heapsize
GCL_MULTIPROCESS_MEMORY_POOL
bool false aggregate allocation across multiple
processes
Just set GCL_MEM_MULTIPLE to 0.5 to run in 50% of physical RAM, etc.
The next three variables regulate GC. The basic idea is to trigger GC
based on the recent allocation, with no GC up to a heapsize of
PAGE_THRESH, then lowering the allocation hurdle linearly to ALLOC_MIN
at a heapsize of PAGE_MAX and larger.
GCL_MULTIPROCESS_MEMORY_POOL will likely default to true at release.
This is being tested now.
Take care,
