[TW5] Avoid the "Recent" tab

Avoid the "Recent" tab - http://tiddlywiki.com/#Performance

It would be useful if this could be elaborated on some more.

Is this basically saying don't even click on the Recent tab or is there more to it? Can the Recent tab be disabled?

Hi Mark

It’s pointing out that the “Recent” is time-consuming for the system to generate. With a big wiki there is a noticeable delay when switching to the tab. In such situations, you’d normally want to avoid switching to it unless you really need it.

Can the Recent tab be disabled?

Yes, just delete the tag "$:/tags/SideBar” from the tiddler "$:/core/ui/SideBar/Recent”.

There’s a default limit of 100 entries on the recent changes list which gives an upper limit on how much impact there can be from switching to the “Recent” tab.

Best wishes

Jeremy

Hi Jeremy

So one could set a lower limit to speed things up? (And maybe add a more… link)

Kind regards

Hi Thomas

Yes. But you’d probably get more of an improvement from replacing the current “Recent” tab with a variant that showed a plain list of titles and dates, rather than grouping the tiddlers by day, which is an expensive operation.

I’ve answered the questions here directly, but I’m concerned that a narrow answer can be misleading.

Software developers are taught that premature optimisation is evil; instead, we’re taught to measure, measure and measure again, and make sure that any changes have the expected impact.

So a useful conclusion to be drawn from this thread is not that everyone should go and re-engineer their “Recent” tab, but rather this: if there is a noticeable pause when switching to the “Recent” tab then your wiki probably qualifies as a “big wiki” (or your browser qualifies as a slow browser :).

In that situation, the first thing I would do is think about how I use the wiki, and just avoid the operations that are time consuming. Only as an absolute last resort would I start to customise the wiki, and I would do so with stopwatch in hand to ensure that my efforts were directed in the most effective way.

Best wishes

Jeremy

Ciao Jeremy, Thomas & Mark H.

Just a general comment.

Since TW is one file running in a BROWSER it makes sense to HONE usage to match what you need do most often. In my use of TW I switch OFF as much as possible

PART of the issue is the sheer INEFFICIENCY of major browsers at memory handling. TBH browsers (Firefox, Chrome) cause me more hassle than most anything else on my computer now. Their memory architecture is pathetic.

There is a lesson in that, because TW can only function as well as its host. What is my point? That some issues in TW are nothing directly to do with it, but essentially current browser limits.

Best wishes
Josiah

Thanks, was this information already in the documentation?

I'm very new to TiddlyWiki so may have been looking in the wrong place.
