Hi,
According with IBM Developer
the lotus domino 8 is better than 8.5.
The lotus domino 8.5, should be better than 8.
Thanks,
Anderson
Subject: Maybe looking at the charts the wrong way?
The lower figures would be better that I can see. Also at the end.
Conclusion
From the measurements reported in this article, upgrading to Lotus Domino 8.5 is a positive experience. You can realize substantial I/O reductions, reductions in disk operations per second by 22 percent to 33 percent, and reductions in disk bytes transferred per second by 31 percent to 67 percent. In addition, processor utilization has been reduced by as much as 20 percent. Upgrading to Lotus Domino 8.5 can lower your Lotus Domino deployment total cost of ownership.
Subject: Domino 8.5 Performance - XPages
Also, am I right in thinking there is improved performance with XPages systems using server-side javascript in XPages compared to AJAX calls to lotusscript/java agents in traditional web developments on Domino?
I’ve not seen any information on performance comparisons at client-side on the browser or on server load. But I would preume hat at server-side, having potentially lots of agents running to handle AJAX calls is more of a performance hit than using server-side javascript within XPages.
Does anyone have any knowledge or experience to back up or refute this theory?
Subject: It all depends…
You can write a horribly-optimized backend agent, and/or a horribly-optimized AJAX-enabled XPage.
Genereally speaking, though, XPages will consume a bit more memory footprint up front (e.g. when a user first connects to the server there’s session variables to initialize, memory space, etc.) but after that initial hit things are quick.
Things like AJAX partial updates in XPages will trump legacy Domino web development – you’re talking about a backend agent to get equivalent functionality and the XPage will have much better caching server-side.
The main advantage of XPages is that you can do SO much more than you would with legacy Domino dev. Take the Repeat Control, for example. To repeat anything of significant in complexity with legacy Domino dev you would need to call a backend agent and generate HTML on-the-fly. There’s many scenarios where, with the XPages repeat control, you would never need to do that.

I looked at it and I don’t see it. Care to be more specific?
