Benchmarks are run nightly using <a class="code"
href="https://github.com/cockroachdb/pebble/blob/master/cmd/pebble/ycsb.go">pebble
bench ycsb</a> on AWS m6id.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 different instances) and outliers are
excluded.

<div class="overview">
This benchmark attempts to find the optimal write throughput by
driving more and more load against the DB until a target heuristic
fails (currently a mixture of number of L0 sublevels, L0 files, and
whether the DB has experienced a write stall). These benchmarks are
run nightly using <a class="code"

bench write</a> on GCP n2-standard-32 machines equipped with 16 local
SSDs in a RAID 0 array.
