mutable minor_heap_size : |
(* | The size (in words) of the minor heap. Changing this parameter will trigger a minor collection. Default: 32k. | *) |
|
mutable major_heap_increment : |
(* | The minimum number of words to add to the major heap when increasing it. Default: 62k. | *) |
|
mutable space_overhead : |
(* | The major GC speed is computed from this parameter.
This is the memory that will be "wasted" because the GC does not
immediatly collect unreachable blocks. It is expressed as a
percentage of the memory used for live data.
The GC will work more (use more CPU time and collect
blocks more eagerly) if space_overhead is smaller.
Default: 80. | *) |
|
mutable verbose : |
(* | This value controls the GC messages on standard error output.
It is a sum of some of the following flags, to print messages
on the corresponding events:
| *) |
|
mutable max_overhead : |
(* | Heap compaction is triggered when the estimated amount
of "wasted" memory is more than max_overhead percent of the
amount of live data. If max_overhead is set to 0, heap
compaction is triggered at the end of each major GC cycle
(this setting is intended for testing purposes only).
If max_overhead >= 1000000 , compaction is never triggered.
Default: 500. | *) |
|
mutable stack_limit : |
(* | The maximum size of the stack (in words). This is only relevant to the byte-code runtime, as the native code runtime uses the operating system's stack. Default: 256k. | *) |
|
mutable allocation_policy : |
(* | The policy used for allocating in the heap. Possible values are 0 and 1. 0 is the next-fit policy, which is quite fast but can result in fragmentation. 1 is the first-fit policy, which can be slower in some cases but can be better for programs with fragmentation problems. Default: 0. | *) |
