Revo 2.0.x slow performance - can we diagnose?

Let’s wake up this thread again. So we know now that Wayfinder and GetResources are slow, even if they’re getting simple strings from a small number of resources.

What can be done to speed it up?

Post your snippet calls for both here...
Do you run any other snippets or plugins on the slow pages?

Also, are you sure the performance hit is at the back end? Try running it through ySlow or GTMetrix to see if any scripts or external files are causing the slowdown.

If you’re able to drop a link to the site here too that might help.

Definitely on the back-end. I’m actually really interested in Yahoo’s Exceptional Performance research. I use yslow et al religious, have the o’reilly books, the lot!

Here’s the snippet as run though the Executioner (’Ex’ is the Executioner)

[[!Ex? &tElement=`Wayfinder` &startId=`2` &outerClass=`ul1` &firstClass=`` &hereClass=`` &lastClass=``  &rowTpl=`wfProductList` &level=`1` &fullLink=`TRUE` ]]

The accompanying Wayfinder chunk is:

<li[[+wf.id]] [[+wf.classes]]><a href="[[+wf.link]]" title="[[+wf.title]]">[[+wf.linktext]]</a>[[+wf.wrapper]]</li>

That’s a very pertinent question. Yes, however as you’ll see from the below, the culprit is Wayfinder

Is Wayfinder up to date?

I think so! 2.3.1?

Do you call wayfinder cached?

Not always. Wayfinder has some problems with friendly URLs and the only way to fix it is to set fullLinks to true. That also writes the hostname into the URL. Problem is I have sites with multiple domains pointing to it, so if I cache Wayfinder, you get incorrect domains appearing in those links. So you have to use Wayfinder uncached if you want to show links stating the domain that the user is currently browsing from (versus one which might be cached).

Wayfinder is really quite a pain!

I had trouble with Wayfinder becoming cripplingly slow... the fix was to sorta prime its pump by spoon-feeding it the &includeDocs:

[[!Wayfinder? &startId=`0` &depth=`2`]]

became

[[Wayfinder? &startId=`0` &includeDocs=`[[!listChildIds?&parent=`0` &depth=`2`]]` &cacheResults=`1`]]

That massively improved the speed of the Wayfinder calls and subsequent page loads.

Where can I find listChildIds ? Is it an inbuild function or a package as it’s not in the Extras repository...
