|
mutable minor_heap_size : |
(* |
The size (in words) of the minor heap. Changing this parameter will
trigger a minor collection.
Default: 262144 words / 1MB (32bit) / 2MB (64bit).
| *) |
|
mutable major_heap_increment : |
(* |
The minimum number of words to add to the major heap when increasing it.
Default: 126976 words / 0.5MB (32bit) / 1MB (64bit).
| *) |
|
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: 1048576 words / 4MB (32bit) / 8MB (64bit).
| *) |
|
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.
