Date Fri, 16 May 2014 11:22:47 GMT

Oleg Kalnichevski resolved HTTPCLIENT-1509.

    Resolution: Cannot Reproduce

No worries. Performance tuning is a tricky business.


> Increase DefaultHttpResponseParser buffer size
> ----------------------------------------------
>                 Key: HTTPCLIENT-1509
>                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1509
>             Project: HttpComponents HttpClient
>          Issue Type: Improvement
>          Components: HttpConn
>    Affects Versions: 4.3.3
>            Reporter: Chris Heald
>            Priority: Minor
>              Labels: performance
> DefaultHttpResponseParser allocates a CharArrayBuffer(128), which ends up resulting in
a 128-byte InputStream read. Due to the typical size of an HTTP response's headers, this ends
up doing tens of stream reads per document read.
> Increasing the size of this buffer to something more traditional like 4096 substantially
improved the performance of HttpClient in my high-load reads.
