I have recently installed DNG 5.0.1 from Jazz.net and so far the experience was great: the setup process was simpler, installation was faster and most importantly the Reportable REST API seems to be considerably faster. I understand that the schemas contain additional information that make template design simpler and I’m sure there are many other useful features I’m yet to discover.
All in all 5.0.1 looks to be a great release so kudos to the DNG team.
I want to put some numbers next to the perceived performance improvements. Publishing a 144 pages Word document with all the requirements (https://giediprime:9443/rm/publish/text/*) from the JKE Banking example takes ~34 seconds with RPE 1.3 and DNG 5.0.1 out of which ~24 is data retrieval.
Publishing a single requirement (https://giediprime:9443/rm/publish/text?resourceURI=_ca9e1108e8eb4473811c2501d5a87968) takes 1 second out of which data the retrieval time is 0.3 seconds.
In my tests RPE and DNG are running on the same machine so in a real usage scenario network latency has to be considered. Even so this shows that DNG is now much faster when it comes to serving the data.
