---------------------------------------------------------------------
It's controlled environment (local network, HTTP server setup is under my
control), so the issue should not be due to network or server, also executed
the tests multiple times and with the same outcome.
Since HttpClient is the layer I am directly interfacing with, I thought the
issue investigation can start from there and that it might be due to some
Windows-specific default configuration done by the HttpClient, e.g. one thing I
am considering testing is enabling the TCP No Delay feature (not sure if that
is different on Linux / Windows).
Anyway, it seems I need to do more investigation on my own and if found more
evidence that there is HttpClient-specific issue, go back with my findings here.
I guess this means we can resolve the issue.
Thanks,

> Key: HTTPASYNC-96
> URL: https://issues.apache.org/jira/browse/HTTPASYNC-96
> Project: HttpComponents HttpAsyncClient
> Issue Type: Bug
> Affects Versions: 4.1.2
> Environment: Windows 7 x64
> Reporter: Stoimen Gerenski
>
> Using custom instance of the client with pretty much standard configuration:
> IOReactorConfig config = IOReactorConfig.DEFAULT;
> IOReactor ioreactor = new DefaultConnectingIOReactor(config);
> PoolingNHttpClientConnectionManager cm =
> new PoolingNHttpClientConnectionManager(ioReactor);
> cm.setMaxTotal(100);
> cm.setDefaultMaxPerRoute(1);
> CloseableHttpAsyncClient client =
> HttpAsyncClients.custom().setConnectionManager(cm).build();
> client.start();
> For writing the bits on disk, used ZeroCopyConsumer.
> Downloading 11 files in total with total size 1,6 GB from the same server.
> Using the same build, downloaded on Linux for 1 minute and on Windows for 4
> minutes.
> Tested with both Java 7 and 8 JREs on the Windows machine - same result.
