Just out of sheer curiosity I ran a Warre for two years. My Warre adventure was just one single hive so factor that in how you consider my experience, which is very little. I made four boxes, a Warre style bottom board, quilt box, 1 gallon top feeder, and Warre style gabled cover.
By the numbers. My Warre had the standard 30 cm square 21 cm high boxes. My state requires that all beehives have removable frames. My frames had sidebars but no bottom bar , giving me a comb face area of 502 cm[sup]2[/sup], or 78 in[sup]2[/sup].
A Langstroth medium frame has a comb face area of 87 in[sup]2[/sup]. A Langstroth deep frame is 136 in[sup]2[/sup]. A fully drawn Warre comb is 89% the size of a Langstroth medium frame and 57% of the area of a Langstroth deep. The Warre has 8 top bars and is 71% the total comb are of a 10 frame medium super.
OK, that's the numbers, but my actual yield was lower a lot lower than 71% of a medium super. If you manage as Abbe Warre did you nadir boxes, that is you place empty boxes on the bottom. Wax production is at the bottom of the stack. The bees should store honey as brood hatches out above, migrating the brood nest down. I found that the bees used boxes 1, 2, and 3 for brood, keeping in mind that with nadiring, box 1 is not fully drawn and when box 1 is drawn you nadir an empty box.

So at the end of September this is how my hive typically was
4: (top) Honey, no brood, but not completely back filled from hatched brood. Frames 1,8 filled and capped, top half of other frames capped, the rest was uncapped and still being back filled.
3: Brood in the lower half of frames 3,4,5. Frames 1,8, filled with honey, 2,7 have a small amount of brood, pollen, uncapped honey and nectar. Honey dome above brood
2: Brood. Honey and pollen stores on frames 1, 8.
1: Partially drawn frames, brood, pollen.
Because of that I could never harvest the equivalent of an entire box. At least because I had frames I could pull the outer combs in box 3 which were usually full and capped and exchange them for some of the incomplete frames.
Each year my crush and strain harvest from the Warre was about 20 lbs. Because I was using a modified Warre with frames I did make an attempt at extraction. I ended up with a colossal mess in the extractor. I suppose if you had a basket to support the comb you could be able to extract instead of crush and strain.
Beekeeping is highly regional, and with a longer season I probably could have gotten box #1 drawn out and maybe had more brood moved down and more capped honey above.
The single biggest problem I encountered was equipment compatability. My other hives are Langstroth. If you had a lot of Warres that might not be an issue, but it is something you will want to think about.
I have exited my Warre. The gear is now stacked up alongside my garage and I don't have any plans to use it again. I may sell it. This is just one person's curiosity driven experience, there are some people on here with lots of Warres who get production from them. However, having played with one, IMO, there is a reason that Langstroths became more popular that Warres.
