> Performance degradation in attachment logic in CXF 2.2.4
> --------------------------------------------------------
>
> Key: CXF-2544
> URL: https://issues.apache.org/jira/browse/CXF-2544
> Project: CXF
> Issue Type: Bug
> Affects Versions: 2.2.4
> Reporter: aaron pieper
> Attachments: CxfBug1.java
>
>
> AttachmentDeserializer attaches a DelegatingInputStream to the message, which
> contains the attachment body. The performance of this InputStream has been
> significantly degraded from CXF 2.2.2 to CXF 2.2.4. For example, a 55
> megabyte file used to take around three seconds to parse - now it takes over
> one minute.
> I've attached a performance test which demonstrates the issue, using an 8
> megabyte file. In CXF v2.2.2, this test takes a fraction of a second to run.
> In CXF v2.2.4, this test takes about 10 seconds on my machine.
> I tried to track down the cause of the degradation. AttachmentDeserializer
> line 206 calls "new InternetHeaders(stream)" which takes a long time to
> complete. Since CXF v2.2.2 and CXF v2.2.4 use the same version of this
> InternetHeaders class, I believe it must be a change in the way the stream is
> being put together.
