> HttpReplicator uses a lot of CPU for large files
> ------------------------------------------------
>
> Key: LUCENE-5599
> URL: https://issues.apache.org/jira/browse/LUCENE-5599
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/replicator
> Affects Versions: 4.7.1
> Reporter: Christoph Kaser
> Assignee: Shai Erera
> Priority: Minor
> Fix For: 4.9, 5.0
>
> Attachments: HttpClientBase.java.patch
>
>
> The method responseInputStream of HttpClientBase wraps an InputStream in
> order to close it when it is done reading. However, the wrapper only
> overwrites the single-byte read() method, every other method is delegated to
> its parent (java.io.InputStream). Therefore, the more efficient read-methods
> like read(byte[] b) are all implemented by reading one byte after the other.
> In my test, it took 20 minutes to copy an index of 38 GB. With the provided
> small patch, this was reduced to less than 10 minutes.
