Hi Guys,
This question has been asked before but on old versions of TW - as far as I can search. I would like to know the latest wisdom on this question.
Many thanks.

aide from the initial load time I don't think that file size is a good indicator of performance. The wikitext complexity seems to be what determines performance.

That is good to know.

That depends on your computer.
I use several ranging from a Amazon Kindle Fire tablet to desktop that is a few years old. Nothing larger than about 4 mb will work acceptably with the tablet whereas the desktop starts to show signs of bogging down with the Bible Tiddlywikis which are about 11 mb with about 35,000 tiddlers. Certain operations such filtered lists are unacceptably slow on my desktop. Even if testing a tiddler for whether it meets filter criteria only takes a fraction of a second, when it has to do it 31000 times for a single list and depending on what is being displayed such as a recent list several times that, it will become noticeable. On a slower computer, it will become unacceptable. As Jed said, complex tiddlers will also slow the process down.
My desktop has never succeeded in importing the entire Bible wiki into the newer version of TiddlyWiki. I suspect that has to do with how TiddlyWiki handles imports. My guess is that it attempts to read the entire wiki into a temporary tiddler and then converts the selected tiddlers. If that's true then the amount of free ram would be the limitation.
In any case, I find the practical upper limit is in the range of 30,000 - 40,000 tiddlers and somewhere in the 12 mb range.

One of the biggest differences is when you input. There apparently is some sort of re-iterative loop going that can't be turned off. It makes typing really slow on big files and/or slower (tablet) machines. There was supposed to be a fix that would let you dial down the effect, but I set it low and high and it didn't make any difference.
