guix package --search slow ?

[zimoun]

Dear,

When searching packages with `guix search`, it appears to me slow;
especially compared to `aptitude` of Debian.

Say on my machine:

$ time guix package --search=python-numpy | recsel -p name -
name: python-numpy
name: python-numpy-documentation
name: python-numpydoc
name: python2-numpy-documentation

real    0m11.864s
user    0m1.160s
sys     0m0.212s


$ time aptitude search python-numpy
i A python-numpy                    - Numerical Python adds a fast array facilit
v   python-numpy-abi9               -
v   python-numpy-api10              -
p   python-numpy-dbg                - Fast array facility to the Python language
v   python-numpy-dev                -
p   python-numpy-doc                - NumPy documentation
p   python-numpydoc                 - Sphinx extension to support docstrings in

real    0m3.219s
user    0m0.656s
sys     0m0.088s


I am not sure to exactly understand how the search works.
Basically, a "big" `fold' is done on `%package-module-path' and there
is no caching. Right?

What should be done to improve the search speed?


All the best,
