Performance improvements

[TheMrZZ]

Why?

Using a high number of recursive If was slowing down the compilation.

Profiling showed the bottleneck was handleConflict, a O(N) operation that happens everytime we add a new Node.

The fix

I switched the resourceNodes Set to a "custom" Map class, ResourceNodesMap. This automatically manages the Map keys by concatenating the packType and the path components.

Performance improvements

Before

• Generating 1500 nested if took 33.430s
• Generating 100k sequential if took 17.02s

After

• Generating 5000 nested if now takes 0.889s (x37 🚀)
• Generating 100k sequential if now takes 2.254s (x7.5 🚀 )

More generally, the new O(1) complexity means Sandstone will better scale on large projects.
