* Header
Emacs variables are dynamically scoped. That's unusual for most languages, so disable it here, too

* First start
These functions updates config.el whenever changes in config.org are made. The update will be active after saving.

* Performance Optimization
** Garbage Collection
Make startup faster by reducing the frequency of garbage collection.
Set gc-cons-threshold (default is 800kb) to maximum value available, to prevent any garbage collection from happening during load time.

#+BEGIN_SRC emacs-lisp :tangle early-init.el
(setq gc-cons-threshold most-positive-fixnum)
#+END_SRC

Restore it to reasonable value after init. Also stop garbage collection during minibuffer interaction (helm etc.)

Fava is strongly recommended.

cd /opt
python3 -m venv fava
source ./fava/bin/activate
pip3 install wheel

#+END_SRC

Start fava with fava my_file.beancount

It is accessable on this URL: [[http://127.0.0.1:5000][Fava]]
Beancount-mode can start fava and open the URL right away. 

* Stuff after everything else
Set garbage collector to a smaller value to let it kick in faster.
Maybe a problem on Windows?
