DXL Preferences

In the Advanced section of the Preferences dialog box, you find this page, DXL. DXL is an abbreviation for Domino XML, where XML again is another abbreviation for eXtensible Markup Language. In short, DXL is the XML variant for describing Domino data.

List Fields use DXL to parse Domino information during High Quality Rendering (HQR).

The DXL processor in Lotus Notes can be quite slow, especially if the Notes document contain large images or attachments. Since it try to decode each one of them into Base64-code, the DXL process itself make take a while.

In order to speed up the user experience in List Fields, data from Domino is parsed in several stages. The first stage is to get a plain text representation of the content. This process is normally very quick and will therefore quickly show text data in List Fields. The second stage is to render richtext content with better quality, so called High Quality Rendering. This process involve DXL to parse attachments and images.

If you experience slow results in List Fields, the reason might therefore be that the document contain large attachments or images, and that DXL takes a long time to process them.

To avoid this slow processing, you might set some thresholds for the High Quality Rendering.

• Only process DXL when attachments are within limits. This option control whether all other options are activated or not. When disabled, as the default setting are, List Fields will process any document with DXL, and thus be slow. When enabled, you can set the threshold size in kiloBytes
• Size in kB. The threshold size in kiloBytes. In our experience DXL has trouble when attachments exceeds 1 MB, so try to keep the threshold below that.
• The limit is for all attachments combined. Select this option to set a total threshold for all attachments combined. For example, if the threshold is set to 1024 kB, and you have a document with 5 attachments, each at 250 kB, this threshold will stop DXL processing since the total size of attachments is 1250 kB.
• The limit is per attachment. Or, select this option if you want to have a maximum size per attachment. If we have the same example as above, List Fields will process the document normally with DXL, since none of the individual attachments exceeds 1024 kB.

Note that you can abort List Fields at any time, even if the DXL processing hasn't finished. List Fields is a true multitasking application, and you can at all times operate the user interface, even if hefty processing happens in the background!
