GCMH - the Garbage Collector Magic Hack

Enforce a sneaky Garbage Collection strategy to minimize GC interference with user activity.

During normal use a high GC threshold is set.

When idling GC is triggered and a low threshold is set.

A more detailed explanation of the rationale behind this can be found at:

• WARNING

  In case Emacs is used in a system already under severe memory pressure be sure to understand how GCMH works and trim gcmh-high-cons-threshold accordingly. Default value may be to big and/or GCMH may not fit your use case.

Usage

Add into your .emacs

(add-to-list 'load-path "path-to-gcmh-here")
(gcmh-mode 1)

If this is done at the beginning of your .emacs start-up time should also benefit form it.
