From b01ee67cb5860d70e5a88af3c25b44d1ecaf0579 Mon Sep 17 00:00:00 2001 From: Will Newton Date: Wed, 11 Sep 2013 15:47:12 +0100 Subject: benchtests: Add malloc microbenchmark Add a microbenchmark for measuring malloc and free performance with varying numbers of threads. The benchmark allocates and frees buffers of random sizes in a random order and measures the overall execution time and RSS. Variants of the benchmark are run with 1, 8, 16 and 32 threads. The random block sizes used follow an inverse square distribution which is intended to mimic the behaviour of real applications which tend to allocate many more small blocks than large ones.
