* Pufferfish description *
|
|
|
|
When executing getCoordinateKey for entities (a hotpath), the JVM is
|
|
required to repeatedly cast doubles to longs. The performance impact of
|
|
this depends on the CPU architecture, but generally switching between
|
|
FPU and ALU incurs a significant performance hit. The casted/rounded
|
|
data is already available in the blockPosition struct, so we use that
|
|
instead of re-doing the casting.
