I had the idea of using burrows to reduce pathfinding and thus increase FPS...

Just to limit dwarves to places they should never need to go - I.E. a weaver never needs to go down to the forges.  Haulers would be limited to being inside the fortress.  It would also be a good way to prevent sock syndrome, because everyone is already in burrows.

Is this viable, or will dwarves still check paths outside of the burrow?

Also, butchering all the cats.

[Roraborialisforealis]

Yes. And whine about stuff that isn't in it. All you get is a lot of very pissed off announcements. Traffic zones is what you want.

[Sphalerite]

Burrows have no effect on pathfinding.  Burrow assignments control what dwarves do, but not where they walk.  The pathfinding code ignores burrow assignment.

It's still a good idea to use burrows to limit dwarves to areas they actually need to be in, but it's not going to help pathfinding much.

[DrGravitas]

I also highly suggest judicious use of traffic-density designators, even though they can't be assigned to particular dwarves (or stop them from charging after socks.) Nothing reduces the pathfinding time better than telling the algorithm that this node tile is too costly to even bother expanding, unless it's all out of options.

Use them all the time in my high population forts, to make highways with on and off ramps to the more common local destination groups. Heh, even took the highway metaphore literally once and built an elevated road system in the surrounding territory so I could maximize the forest growth to fuel my insatiable (and magma-less) steel works industry.

[Vehudur]

What should I set the weight of the restricted traffic areas as (per tile, default is 25 I think)

[DrGravitas]

I think that's fine. As I recall, the regular tiles are only rated a 1 or 5 or something.

[krenshala]

Its 1 (restricted), 2 (low), 5 (normal), 25 (high) for traffic levels.

[acetech09]

That's backwards. 1 high traffic, 2 normal, 5 low, 25 restricted.

[Girlinhat]

Yeah, it means that a dwarf will try to path through 5 tiles before pathing through a restricted zone, and if they've got a nice High passage, then it's 25 times more costly.  If there happens to ever be a job in the restricted zone, it will cost more pathfinding, but this is infinitely compensated by the everyday pathfinding.

If you've got all your worthwhile things underground, or above ground in a tower, or something else very localized, then restricting the entire surface can reduce pathing quite a bit, because let's face it, your dwarves are only loitering between the farm, the stockpiles, and the dining hall.  They don't need to path through the bright and happy forest to fetch their kitten tallow roasts.

No, they'll try to path through 12 tiles before pathing through a restricted zone.  2 is normal, not 5.

[Girlinhat]

Oh, derp, then yeah!  Even better!
