Memory usage of history?

[Dominik Vogt <vogt@xxxxxxxxxxxxxxxxxx>]

Could someone please explain the implications of having a large
history file?  Does an interactive zsh read the history file into
private memory upon startup, or how does this work?  Is there a
way to reduce memory and cpu consumption somehow?  (A colleague
says his zshs use 200 MB memory each with a history size of a
million lines).

Ciao
