Pebble Benchmarks

Last updated

Benchmarks are run nightly using pebble bench ycsb on AWS c5d.4xlarge machines equipped with local SSD storage. The AWS instances show remarkably high instance to instance performance variability. In order to smooth out that variability the benchmarks are run multiple times each (using difference instances) and outliers are excluded.
