Yet another experiment in the NodeEncoder which could improve performance.
This focuses on removing as many branches from the code as possible through 2 optimizations:
newEntry
field in lookup entries and instead ofgetOrAddEntry
use the splitgetEntry
andaddEntry
. This API, although less elegant, does reduce the number of branches by 1, because we have to check if the entry is new or not only once, instead of twice. This also makes it so that we can store just one integer in the hashmap per entry, instead of an object with 3 fields. This should help with memory bandwidth slightly.lastId + 1 == id ? 0 : id
. It should help, especially because these branches were close to returns.
