particle bind

[nayan]

Hey there,
I have noticed a performance degradation in particle bind calculation.
I had 1500000 particles in position volume, when applied first particle bind - it was very fast, but when I applied again another particle bind, it was little slow - which is understandable as its calculating two particle bind, but when I deleted anyone particle bind, I should expect to be fast, but instead the remaining particle bind took a whole lot more time to calculate bind than before.

Particle Binds can be broken, but they are not deleted from memory until the sim is refreshed. The reason is because it's possible to restore deleted binds and such, so they have to be retained in the overall bind data structures in case they need to be referenced again, even after breaking. For this reason, it'll be slower to iterate them all even if many are broken and seemingly deleted.

You can always use the tyProfiler to see exactly which parts of the sim are slow...
