A few quick observations. Note that I work on a very high end desktop that makes it difficult to gauge performance accurately. For example, the second Noto document from TT loads in a few seconds for me. However, comparing the performance of Streams and Noto might be insightful.
These are averages of 3 runs in Streams and Noto with the tiddly toolmap imported. *NOTO* *All top level items collapsed : * mainRender 4733ms mainRefresh 1157ms *All items expanded: * mainRender 5497ms mainRefresh 1220ms *STREAMS* *All items collapsed* mainRender: 222ms mainRefresh 23ms *All items expanded:* mainRender: 2360ms mainRefresh 184ms What is interesting here is that Streams is much faster when the items are collapsed. Note that streams has a lot of complexity added in the way of filter runs for determining collapse state and drag and drag state, so I would expect Noto to be as fast if not faster. So are the sub levels in Noto rendered even if they are not shown? Also crucially, the editing experience in Streams seems normal, not any slower than with just one tiddler in the stream. Even if the faster hardware is masking some of the problem, it shows that Noto is suffering far more of a performance hit when editing. I think it is important to distinguish between rendering performance, when first opening the tiddler, versus refresh performance, when typing etc. The slow performance in Noto reminds me of what happens when editing forces a refresh of the containing tiddler or widget. This could be as simple as a set or vars widget that is being refreshed due to a containing tiddler being changed, which refreshes all the content inside those widgets. One way to resolve this is to rework the logic for filters used to avoid such a situation. Another workaround is to edit in draft/temp tiddlers, and only save back to the original tiddler when the user actually saves. This would mean that the surrounding content would only refresh when you save the tiddler, as opposed to on every key stroke. An intermediate step that might offer some help is setting the throttle.refresh field on the tiddler being edited. Note also that somewhere in tiddlytoolmap in one of the list items is the code for a filter run, that will end up listing close to all the tiddlers in the wiki!! I've removed this in my copy. I wouldn't be surprised if that is exacerbating the problem. I don't have the opportunity to look at the Noto code at the moment, but hopefully this might lead you in the right direction with regards to performance issues.
