+#Whether to use an alternative strategy to make structure layouts generate slightly even faster than
+#the default optimization this mod has for template pool weights. This alternative strategy works by
+#changing the list of pieces that structures collect from the template pool to not have duplicate entries.
+#
+#This will not break the structure generation, but it will make the structure layout different than
+#if this config was off (breaking vanilla seed parity). The cost of speed may be worth it in large
+#modpacks where many structure mods are using very high weight values in their template pools.
+#
+#Pros: Get a bit more performance from high weight Template Pool Structures.
+#Cons: Loses parity with vanilla seeds on the layout of the structure. (Structure layout is not broken, just different)
