+#  DateTimeFormatBenchmarks
+
+JMH based benchmarks to evaluate parsing a timestamp (with zone) to a ZonedDateTime (single threaded case)
+
+##  Participants:
+* java.time.ZonedDateTime#parse with java.time.format.DateTimeFormatter
+* org.apache.commons.lang3.time.FastDateFormat (with conversion)
+* org.joda.time.format.DateTimeFormat (with conversion)
+
+## To build & run
+`gradlew jmh`
+
+## Results
+
+| Benchmark                                     | Mode  | Cnt | Score      | Error      | Units |
+| ----                                          | ----- | --- | ---------: | ---------: | ----- |
+| ZonedDateTimeBenchmark.zonedDateTimeParse     | thrpt | 200 |  98270,686 | ±  407,439 | ops/s |
+| ZonedDateTimeBenchmark.fastDateFormat         | thrpt | 200 | 594823,336 | ± 3296,509 | ops/s |
+| ZonedDateTimeBenchmark.jodaDateTimeFormatter  | thrpt | 200 | 728459,747 | ± 5566,384 | ops/s |
