                 Key: ABDERA-277
                 URL: https://issues.apache.org/jira/browse/ABDERA-277
             Project: Abdera
          Issue Type: Bug
    Affects Versions: 1.1.1, 1.1, 1.0, 0.4.0
         Environment: Seen on Jetty7 and in local unit-tests.
            Reporter: Olve S=C3=A6ther Hansen
            Priority: Critical


When I am creating a feed with a lot of entries, say 2-3000, the JSON seria=
lization is horribly slow. XML serialisation is very fast in comparison.
I am using Abdera together with Jersey, via Jersey integration.=20

Using curl and Jersey content-negotiation the xml-file downloaded instantel=
y. The json-file took as much as a minute and a half, and as little as 22 s=
econds.=20
Some investigation lead me to the excessive calls to flush in the JSONStrea=
m-class.
https://github.com/apache/abdera/blob/abdera-1.1.1/extensions/json/src/main=
/java/org/apache/abdera/ext/json/JSONStream.java

My proposal for a fix is in the attatched patch.

I hope someone can put this in as soon as possible. I will have to make a l=
ocal "fork" for this fix until it is released through proper channels.=20
