> When I am creating a feed with a lot of entries, say 2-3000, the JSON ser=
ialization 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 instant=
ely. The json-file took as much as a minute and a half, and as little as 22=
 seconds.=20
> Some investigation lead me to the excessive calls to flush in the JSONStr=
eam-class.
> https://github.com/apache/abdera/blob/abdera-1.1.1/extensions/json/src/ma=
in/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=
 local "fork" for this fix until it is released through proper channels.=20
