+#### tick-rates

+```
+Good starting values:
+
+    sensor:
+        villager:
+          secondarypoisensor: 80
+          nearestbedsensor: 80
+          villagerbabiessensor: 40
+          playersensor: 40
+          nearestlivingentitysensor: 40
+      behavior:
+        villager:
+          validatenearbypoi: 60
+          acquirepoi: 120
+```
+
+This decides how often specified behaviors and sensors are being fired in ticks. `acquirepoi` for villagers seems to be the heaviest behavior, so it's been greately increased. Decrease it in case of issues with villagers finding their way around.
