Stoimen Gerenski commented on HTTPASYNC-96:
-------------------------------------------
It's controlled environment, so the issue should not be due to network, 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 the 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.
