Thanks for your reply, upvote and resteem, it is appreciated!

The route itself was about 80 meters of climbing, not to much, considering that the difficult part was only 10 meters. It took about two hours to climb it i guess, didn't pay that much attention to the time as it was short and we didn't have to worry about rappeling in the dark.

An ice drill can be placed pretty fast. You unclip it from the harness, slam it into the ice so it doesn't fall down when you try to turn it, and after a couple of twists (where it really gets into the ice) you try to get it in as fast as possible. So if the ice is good, and you're standing relaxed you can do it in around 30 seconds. If the ice is not really good and you need to search a little bit it can take up 2 to minutes. If it takes longer you probably are better off climbing a little bit further hoping for better ice.

You place as much protection as needed, if it is really difficult i prefer to have in a screw every 2 / 3 meter (although falling is not really an option), but in easy parts a piece every 10 meters is not an issue. If you can't get through a part, you can hang in your anchor point, screw in the next, and repeat until you can climb again. It works, but takes some time.

Axes are quite good protection. If you want to rest, you can hang your rope over an axe and just hang from it. Or if you want to place an ice-screw, you can clip the rope to your axe so you are secured. You can even use them as an extra anchor point for your belay if needed.

Thanks again for your post, and if you have more questions, feel free to ask :-)
