EMACS SPEED UP 1000 percent

I'm still NOT satisfied with my Emacs performance after applying below tricks:

autoload packages
idle-load packages
compiling \*.el to \*.elc

After some research, I found I could make my Emacs 1000% fast in 1 minute. Please note I'm talking about the general performance not just startup time.

The solution is really simple. Since I'm a Linux guy and my computer got enough (24G) memory. I can place my setup on memory only.

Step 1, insert below line into /etc/fstab and restart computer:

tmpfs       /tmp        tmpfs       nodev,nosuid,size=8G    0   0

Step 2, run the script "emacs2ram":

#!/bin/sh
if [ -z "$1" ];then
    echo "Usage:"
    echo "  emacs2ram start"
    echo "  emacs2ram restore"
    exit 1
fi

if [ "$1" == "start" ];then
    backup=emacs.d-backup
    link=.emacs.d
    volatile=/tmp/.emacs.d-$USER

    IFS=
    set -efu

    cd ~/

    if [ ! -r $volatile ]; then
        mkdir -m0700 $volatile
    fi

    # link -> volatie does not exist
    if [ "$(readlink $link)" != "$volatile" ]; then
        # backup project at first
        mv $link $backup
        # create the link
        ln -s $volatile $link
    fi

    if [ -e $link/.unpacked ]; then
        echo "Sync .emacs.d from memory to backup ..."
        rsync -avq --delete --exclude .unpacked ./$link/ ./$backup/
        echo "DONE!"
    else
        echo "Sync .emacs.d from disk to memory ..."
        rsync -avq ./$backup/ ./$link/
        touch $link/.unpacked
        echo "DONE!"
    fi
else
    echo "Moving .emacs.d back to disk ..."
    backup=$2-backup
    link=$2
    volatile=/tmp/$2-$USER
    cd ~/projs
    rm $link && mv $backup $link && rm -rf $volatile
    echo "DONE!"
fi

That's all! Please enjoy Emacs as usual. The original script is from ArchLinux Wiki. I learned this technique eight years ago.

I'm just wondering why I need eight years to apply it?

BTW, I've also moved all my projects into memory, using similar scripts.

UPDATE: I also publicize my project-managing script at gist. It's almost same as emacs2ram.
