---------------------------------------
Hi guys,
I noticed that the history detail view is quite slow for getting the task
details.
I've run a WordCount with a DOP of 400 and the system needs 27 seconds to
retrieve the JSON data.
It spends 86 ms until the server starts sending, the transmission takes 27
seconds. I think the bandwith is not a problem here because its only 500kb and
all systems have a good network connection. I suspect that the JSON strings are
generated very inefficiently.
Can you take a look into this?
