ARROW-456: Add jemalloc based MemoryPool Runtimes of the `builder-benchmark`: ``` BM_BuildPrimitiveArrayNoNulls/repeats:3 901 ms 889 ms 1 576.196MB/s BM_BuildPrimitiveArrayNoNulls/repeats:3 833 ms 829 ms 1 617.6MB/s BM_BuildPrimitiveArrayNoNulls/repeats:3 825 ms 821 ms 1 623.855MB/s BM_BuildPrimitiveArrayNoNulls/repeats:3_mean 853 ms 846 ms 1 605.884MB/s BM_BuildPrimitiveArrayNoNulls/repeats:3_stddev 34 ms 30 ms 0 21.147MB/s BM_BuildVectorNoNulls/repeats:3 712 ms 701 ms 1 729.866MB/s BM_BuildVectorNoNulls/repeats:3 671 ms 670 ms 1 764.464MB/s BM_BuildVectorNoNulls/repeats:3 688 ms 681 ms 1 751.285MB/s BM_BuildVectorNoNulls/repeats:3_mean 690 ms 684 ms 1 748.538MB/s BM_BuildVectorNoNulls/repeats:3_stddev 17 ms 13 ms 0 14.2578MB/s ``` With an aligned `Reallocate`, the jemalloc version is 50% faster and even outperforms `std::vector`: ``` BM_BuildPrimitiveArrayNoNulls/repeats:3 565 ms 559 ms 1 916.516MB/s BM_BuildPrimitiveArrayNoNulls/repeats:3 540 ms 537 ms 1 952.727MB/s BM_BuildPrimitiveArrayNoNulls/repeats:3 544 ms 543 ms 1 942.948MB/s BM_BuildPrimitiveArrayNoNulls/repeats:3_mean 550 ms 546 ms 1 937.397MB/s BM_BuildPrimitiveArrayNoNulls/repeats:3_stddev 11 ms 9 ms 0 15.2949MB/s ``` Author: Uwe L.
