602: Use mimalloc as the default allocator r=Kerollmops a=loiclec ## What does this PR do? Use mimalloc as the global allocator for milli's benchmarks on macOS. ## Why? On Linux, we use jemalloc, which is a very fast allocator. But on macOS, we currently use the system allocator, which is very slow. In practice, this difference in allocator speed means that it is difficult to gain insight into milli's performance by running benchmarks locally on the Mac. By using mimalloc, which is another excellent allocator, we reduce the speed difference between the two platforms. Co-authored-by: Loïc Lecrenier <loic@meilisearch.com> |

Milli
Fuzzing milli
Currently you can only fuzz the indexation. To execute the fuzzer run:
cargo +nightly fuzz run indexing
To execute the fuzzer on multiple thread you can also run:
cargo +nightly fuzz run -j4 indexing
Since the fuzzer is going to create a lot of temporary file to let milli index its documents I would also recommand to execute it on a ramdisk. Here is how to setup a ramdisk on linux:
sudo mount -t tmpfs none path/to/your/ramdisk
And then set the TMPDIR environment variable to make the fuzzer create its file in it:
export TMPDIR=path/to/your/ramdisk
