Overview

Median values for each library. For every metric, lower values are better.

Library	Time	Instructions	Peak memory	Allocations
JBird	93.5 μs	2.0M	30.5 MB	668
Foundation	182.4 μs	4.1M	332.4 MB	986

All Metrics

The mean of each metric, and its percentiles from p0 (the lowest sample) to p100 (the highest sample). For every metric except throughput, lower values are better.
