Emacs' garbage collector waits until a byte threshold has been reached before executing. +> This value feels relatively low for a modern computer - only `800KB`. + +Once threshold is reached the garbage collection process takes time, and causes the stutter. If you want to see just how often this triggers the GC, try setting `garbage-collection-messages` to non nil (you might be surprised how often it triggers). As with most things in Emacs, you can tune this behaviour. + +Opinions differ. +- Some people recommend **increasing** the threshold, leading to longer times without triggering the GC but longer stutters. +- Others recommend **lowering** the threshold, causing more frequent GC triggers but smaller stutters. +- The minibuffer (especially with packages like `vertico`) can use a lot of memory, so some [recommend](https://bling.github.io/blog/2016/01/18/why-are-you-changing-gc-cons-threshold/) increasing the threshold only when using it. + +# The Solution +In my opinion, the best solution is to garbage collect **when idle**.
