338969 - loading an instance and populating a select1 with its data is very slow

Status: RESOLVED DUPLICATE of bug 329935

(Core Graveyard :: XForms, defect)

Description

[Maria Soler Climent]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; ca; rv:1.8.0.3) Gecko/20060513 Ubuntu/dapper Firefox/1.5.0.3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; ca; rv:1.8.0.3) Gecko/20060513 Ubuntu/dapper Firefox/1.5.0.3

We load an instance with xml data and populate a select1 with this. We do this because this data has to be dinamically generated. Even if we us an xml local file, the loading of this data has a delay of some minutes... This delay depends on the size of the xml, but even with not so big files is larger than it should be.It is not usable.

Reproducible: Always

Steps to Reproduce:
1. open the form attached
2. you'll see the time it will take to load the data

Confirmed. Ouch it's slow on v0.5

Comment 6

[Allan Beaufour]

This is fixed by bug 329935. What takes around 3 minutes on a 0.5 release build, takes 7 seconds on a debug trunk build. Still not blazingly fast, but a giant improvement.

So in other words, next release should improve matters a lot.
