several scripts are very slow in Camino (and possibly FF)

[Denis-de-Bernardy]

Just realized this upon comparing it with Safari while investigating a css bug.

In Safari it's nice and snappy. In Camino (and possibly FF), there is 1s or more of lag when:

• TinyMCE is loading in the editor
• The widgets screen is loading

It seems related to performance differences between the jQuery selectors (dunno about the TinyMCE equivalent) in script engines.

the one for the admin menu only happens on the widgets script.

What version of Safari?

Safari 3.2 is faster than Fx 3.0. Safari 4 is *very* fast. Fx 3.1/3.5 is about as fast as Safari 4, but Fx 3.0 is much slower. I suppose the current stable version of Camino uses the same engines as Fx 3.0.

Camino 1.6.7.

Safari (3.2.3) is fine.

Hmm...

Camino 1.6.7 runs on Gecko 1.8.1, the same engine Fx 2 used. That’s very slow compared to the speed of engines in stable and beta browsers today (and even more slow considering the increasing amount of JS used in pages).

So, this slowness is to be expected.

See this table here for reference:

that explains a lot, yes.

Just FYI, TinyMCE uses Sizzle, just like jQuery.

sorry, wrong ticket
