Browser form extremly slow

[יבש]

One of many browser forms we created has become extremly slow in production.
It would seem that the amount of data retrieved (about 500Kb) from several
web services has a negative effect on the client-side performance of the form
within IE (Firefox performs rather well with the same form, BTW). This
slowdown can be perceived even when simply traversing the fields or moving
the selection from one option button to another or selecting a value from a
drop-down list. It seems that a lot of time is being spent inside core.js; I
am not sure whether the form would be usable if we don't load that script at
all.

Any ideas?

I have a form that exhibits the same behavior. Firefox works really fast
but IE has about a 1-2 sec lag navigating between form fields. Turning
off postbacks didnt fix the problem at all. Not a solution but now you
know you aren't alone.

Hi there,
I am experiencing the same problem with my browser-based form.

Loading the form is fast, but switching between form fields takes for
ages. I already set every field to not do any postbacks, but the form
is still very slow.

The form works a little bit faster with IE7 than with IE6 but it still
takes 2-4 seconds switching between fields.

I have a few data connections that load data on Form Load and one
calculation inside the form.

This is really frustrating.
Any ideas ?

There are known issues with Infopath browser forms. We have a form
that now takes 40 seconds to load in IE6. Firefox it's about half a
second. There was a hotfix available from Microsoft (http://
support.microsoft.com/kb/937206) on request but it didn't seem to help
THAT much on our form.

There are some suggested thigns to try - don't use auto sized text
boxes was on I could remember.

Rich text boxes are the main source of our slow downs.

Another tip would be to check every width and height property and make
sure the value is a static one and not a dynamic one.
