Has it been sped up at all? Last time I used codex (which was with 5.1 I think), it was pretty slow. I mean, it did a fantastic job at figuring out hard bugs across multiple languages ("why is this image not lining up in this server-rendered template?"; Python, JS, CSS, and the template lang) but it took quite a long time. Long enough that I wouldn't want to use it for anything but the most complex things.
