@defopt gc-cons-percentage
The value of this variable is the minimum portion of the heap that
should be allocated before a garbage collection takes place. It is
used only if the specified size is larger than
@code{gc-cons-threshold}.
The value of this variable specifies the amount of consing before a
garbage collection occurs, as a fraction of the current heap size.
This criterion and @code{gc-cons-threshold} apply in parallel, and
garbage collection occurs only when both criteria are satisfied.
As the heap size increases, the time to perform a garbage collection
increases, so in order to compensate, this variable tries to
correspondingly reduce the frequency of collection by letting Emacs
allocate more memory between each collection.

proportion.
