zsh and memory

zsh and memory

[Danny Dulai]

Any hints on how to make zsh not consume as much memory as it does?

I'm not using the zftp or stat modules. Any thing else I can do?

It'd be easier to answer the question if we knew what you ARE doing.
"Is there any way I can get rid of these lumps on my head?  I'm not
hitting myself with a hammer."

Various things you should avoid if memory is a problem include:

    setopt ALLEXPORT
    use large here-documents
    define lots of shell functions without using autoload
    use "zed" (old) or the mapfile module (new) to edit files
    use the new 3.1.6 shell-function-based completion system

The last one is a bit unfortunate, but just "compinit" (without even
trying any completions yet) adds half a megabyte to the RSS of zsh on
my system, and it only goes up from there as functions autload and
start caching their results in shell variables.

I'm just running zsh, defining like 4 very very small functions, like 25
aliases, like 15 completions using compctl, various options set (but not
ALLEXPORT). I'm using vi keybindings, adding like 5 of my own, and not
using anything like zed or any other modules. Never do I use a
here-documents.

Even running zsh -f with no /etc/zshenv existent, will give me a shell
significantly larger than a bash.
