How long does this take for linux?

Pretty slow (on my workstation):

This is pretty specific to the official server. Here are some assumptions (probably others were forgotten): - Docker is available and is used to host the HTTP server on TCP/8080. - A symlink named /srv/elixir-data points to either /srv/elixir-data-a or /srv/elixir-data-b. It contains all projects. Indexing is done by copying the "hot" data to the "cold" location and starting a new container. Signed-off-by: Théo Lebrun <[email protected]>
