As in LispWorks 4.x, the main tool for tuning the GC is the macro
and periodical calls to
, to see how the system behaves.
In the output of
, the allocation in each generation is presented according to the allocation type, which may be useful to decide on possible tuning.
outputs the time spent in garbage collection, whether automatic or called explicitly. The time is shown according to the maximum generation number that was collected and to whether it was a standard garbage collection (automatic and calls to
) or a marking garbage collection (calls to
In addition to
, there are also the functions
. These function can be used to collect information about automatic garbage collection operations.
