Over the last few months I’ve been involved with an application that has needed quite considerable optimisation and architectural modification. A few weeks ago I published a blog post about aspects of developing for performance and then followed up with a discussion about performance and Domino. In this blog I’m going to go into more …
Over the last month or so, I’ve been working on an application that pushes performance quite a bit. Last week I published a blog post about aspects of developing for performance. I’ll be writing a future blog post (maybe more than one) on the approaches I’ve taken for performance. But in this blog post I …
Performance is an area that I have been very aware of with Domino, as I’ve previously blogged about. It’s an aspect I cover in basic XPages training and sessions I’ve done. But before going any further, it’s important to realise performance falls into two distinct areas – developer performance (speed to market) and code performance …
A couple of weeks ago I received an acceptance for one of my session abstracts for IBM Connect 2015 2016. The session is titled “Marty, You’re Just Not Thinking Fourth Dimensionally”: Troubleshooting XPages. The session arose from some blog posts I did this year as well as a number of questions I’ve seen on StackOverflow this …
One of the biggest impacts on performance is the rendered property of components. As I’ve blogged about before, it’s calculated multiple times during a partial refresh. If the rendered property is computed using Expression Language (e.g. #{viewScope.showTheseFields}), the impact is probably not very high: the check goes through the VariableResolver to identify the Java object …
Last week I delivered two sessions at ConnectED. Here are the session slides. BP106 From XPages Hero To OSGi Guru: Taking The Scary Out Of Building Extension Libraries MAS103 XPages Performance & Scalability To download the slides, go to Slideshare, for BP106 (not sure what went wrong with the URL!) and MAS103.
Yesterday I heard that I was accepted for two sessions for IBM ConnectED at the end of January. They are: Title: XPages Performance and Scalability Conference/Track: Track 7: Master Classes Speaker(s): Tony McGuckin; Paul Withers Abstract: This session by Tony McGuckin and IBM Champion Paul Withers is a deep dive on key aspects of the …
The DataView is an extremely powerful control that was added with the Extension Library. I was never a huge fan of the View Control. It was limited in its datasources and layouts. But the DataView accepts any datasource, provides a nice out-of-the-box layout as well as allowing flexibility with facets. Unsurprisingly it took up a …
Some time ago I posted about the number of times the rendered property gets calculated during the JSF lifecycle and the benefits of partial execution. (One caveat is that I haven’t re-tried that since 8.5.x, so more optimisation may have been built into the XPages runtime engine.) One way of optimising calculations in the rendered …

XPages in Notes Client is one area that is receiving constant development. With 8.5.3 we gained Domino server and Notes client preferences XPagesPreload=1 and XPagesPreloadDB=myServer!!myDb.nsf/myXPage.xsp,myLocalDb.nsf/test.xsp. These preloaded the XPages runtime and preloads specific databases. Then with 9.0 we gained the functionality in Notes Client to define XPages that need to run on the server on …
