Fields, Template admin page performance

[Soma]

When on projects with lots of fields (+100), the loading of the setup fields list takes 4-5 seconds. 

What I think could be cool is if they load via ajax. Not sure about details but I use tags often then to group them. Maybe after certain amount of fields and tags, collapse the sections and only load the fields in them when openened.

Just something to think about.

Soma,

I have an install with 100+ fields (seems insane, but this install handles several custom web apps). 

I haven't really noticed setup > fields loading THAT slow, but it does lag a bit.

It's been less of an issue with the "quicklinks" to fields in the new admin themes — which even with 100+ still works great.

I like the idea of of collapsing the fields after a certain number and loading via ajax, especially if it saved the state of the list.

Good call.

Install here 100 fields. no noticeable slowdown.

146 here and growing still, and very noticable slowdown. Other admin pages and Server is fast.

I'm not getting any perceptible slowdown with 100+ fields here. Soma do you have any modules hooking into the rendering on that screen? Considering how quickly the dropdown navigation versions can be generated, I'm guessing the slowdown may have something to do with the calculation of # templates and # pages that are shown. If I can get a copy of your database dump, I could import here and test.

These were actually just converted to AJAX yesterday, so that they don't have to be loaded/rendered on every admin page request. This also removes the 100 field/template limitation that we'd imposed on it.
