They are very low level and for a specialized purpose. ... eg: backlink detection requires the function to create a parse-tree for the tiddler. Then it checks if there is a "link to xxx". It takes the xxx and stores it into an array, that's much easier to check. ... So every lookup for xxx just uses that array, which is much faster. The same is done with alias-backlinks. ... but the detection phase uses a completely different algorithm, while the mechanism is the same.

The different tiddlers are also tagged $:/tags/ViewTemplate. ... To check if a tiddler is tagged that way, we need to check every tiddler in the system. Both shadow and "real" tiddlers. ... The more tiddlers, the more work to do. The above example gives us 2 ways to build indices. 1) use the "prefix" $:/core/ui/ViewTemplate/ and store the "nodes" below it. 2) create a tag-based index for every tag. A possible index structure, that I have in mind here is called radix-trie <https://en.wikipedia.org/wiki/Trie>. Since there is only 1 "main rule" in TW. "The title has to be unique" imo this would be a very good fit. ... Sure we still have "shadow" tiddlers and "real -> system + tiddlers". ... ----------------- Back to your post codes.
