Levo's slow TiddlyWiki

[David Gifford]

Hi all

Twitter user Levo is reporting that their Stroll TiddlyWiki is so slow that even when typing it takes a second or two for the characters to appear.

Levo says the Stroll only has 400 tiddlers, not much tagging, no macros. Levo said "I use the server" - not clear what browser, OS and saver Levo uses.

Any idea what might be happening?

Blessings, Dave

David,

Performance is still an art rather than a science. The key issue is people can ask tiddlywiki to do things they do not realise needs a lot of processing.

• Is this using the standard editor in draft mode?
• Is the browser running out of memory (close all tabs and windows but one and see if it still occurs)
• Is the local disk out of memory/swapping? use normal maintenance practices.
• Change or hide the side bar as it may be being updated somehow with every key stroke
• Have only the tiddler in question open in case changes need to be reflected in other tiddlers on screen.

Additional steps can be taken if one of these things show the "cause".

Regards

Tones

Thanks Tones

I sent Levo the link to this thread, so hopefully they can check the items you mentioned.

Sorry that I wasn't clear enough. I am using the webserver that runs on node.js on my own computer. 

- Yes I am using the standard editor

- I have closed all my tabs on my browsers and any other additional programs and I am still getting the problem

- my local disk still has another 100gb of storage left and I am using an SSD

So closing all my tiddlers actually worked.

Thanks I didn't now about the other tiddlers automatically updating before I closed and saved the tiddler.

Levo,

If you think about it if you had a list of items so tagged, when you tag something else it need to be updated to include the new item.

This immediate update and always "up to date" nature is a key usability aspect of TiddlyWiki. Any change can be reflected anywhere it is referenced (in view) It takes time but you do learn to understand it, that the consequences of one change, must be reflected in what you can see on the screen or it would be out of date, so the less on the screen, the less there is to update. This is normally not an issue, but in some cases this reduces performance because you are asking it to do more.

by closing tiddlers you also reduce the items listed in the side bar open tab etc... every relevant change is also reflected in various tabs in the sidebar, so the side bar can be updated with a change as well. That is why hiding it may also help.

Computers makes doing things very easy, this means we tend to ask it to do more without even thinking about what we are asking it to do, we just expect it.

Regards

Tony

That's still strange. If you only have 400 tiddlers, it should be fast. TW empty.html has about 2000 shadow tiddlers. So an other 400 shouldn't slow it down to a second response time.

Did you import a lot of images?

How does the most complicated filter, that you use look like?

Levo, do you have a lot of tiddlers open in the Tiddlywiki while the TW is slow to show what you are typing? What happens if you close all open tiddlers and then try typing in one open tiddler?
