# Benchmarks are sharded.
#
# Each benchmark (parser, transformer, etc) runs in parallel in a separate job.
# Linter benchmarks are much slower to build and run than the rest, so linter benchmark
# is built in 1 job, and then run on each fixture in parallel in separate jobs.
#
# See https://docs.codspeed.io/features/sharded-benchmarks
