Allocator performance reference
Read time 5 minutesLast updated 7 days ago
The following benchmarks make 150 consecutive allocations per sample set. Multithreaded benchmarks make the full 150 consecutive allocations per worker thread per sample set. The Min of 50 sample sets is compared against the baseline on the far right side of the table. 5 extra sample sets are run as warmup.
All measurments were taken on 12th Gen Intel(R) Core(TM) i9-12900K with 24 logical cores. Unity Editor version: 2022.2.8f1
