Expand description
A benchmarking harness for concurrent key-value collections.
Say you have a concurrent collection (like a HashMap
) and you want to measure how well it
performs across different workloads. Does it collapse when there are many writes? Or when there
are many threads? Or if there are concurrent removals? This crate tries to give you answers.
bustle
runs a concurrent mix of operations (a “workload”) against your collection, measuring
statistics as it goes, and gives you a report at the end about how you did. There are many
parameters to tweak, but hopefully the documentation for each element will help you decide. You
probably want to measure your collection against many different workloads, rather than just a
single one.
To run the benchmark, just implement Collection
for your collection (CollectionHandle
may
end up just being a call to clone
), build a Workload
, and call Workload::run
parameterized by your collection type. You may want to look at the benchmarks for
lock-protected collections from the standard library in benches/
for inspiration.
The crate is, at the time of writing, a pretty direct port of the Universal Benchmark from
libcuckoo
, though that may change over time.
