## java-benchmark

Runtime benchmarking of comparable java techniques.

#### StreamBenchmark

Compares compound inline λ vs method references for two filter

expressions.

Here is a look at average run-time.

machine specs: 4 core, 8 threads, 3.40 Ghz, 16 Gb RAM

```

StreamBenchmark.filterStreamOperationsLarge    avgt       4   666865.390 ±  79848.950   ns/op

```

Compound λ expressions appear to be about 1.5 times faster than

multiple method references.
