Comparing Apache HC 4.0.3 with AsyncHttpClient 1.3.4

HttpClient Benchmark Tentative

Using

    https://github.com/jfarcand/java-http-client-benchmark

demonstrate the performance difference between Apache HC 4 and AsyncHttpClient. Any load numbers produce the same ~3 times performance difference between the client:

Apache Http Client 4.0.3
-------------------------
BenchmarkResult{requestsPerSecond=818.98, threads=5, batches=50, targetRequests=12500, successfulRequests=12500, failedRequests=0, averageRequestTime=1.22ms, averageBatchTime=3.05ms, totalBenchmarkTime=1.52ms}

AsyncHttpClient 1.3.4
---------------------
BenchmarkResult{requestsPerSecond=2579.91, threads=5, batches=50, targetRequests=12500, successfulRequests=12500, failedRequests=0, averageRequestTime=3.87ms, averageBatchTime=9.69ms, totalBenchmarkTime=4.84ms}
