Good point. Under no circumstances whatsoever should the user be expected
to do data entry for 50 items on a single web page unless they items all
happen to be simple checkboxes. This is a known principal in
user-experience architecture and Web site usability. If you need some lab
data or something that backs this up, I can probably find something if I
dig around.
Data entry is a cumbersome process. Users must be incented through the
process by parsing the process itself into manageable chunks and giving
users motivation throughout.
Consider a "wizard"-based data entry metaphor to correct this issue.
Also, make sure that you give appropriate feedback to the user after each
wizard step.
Consider also adding a motivator and possibly even a "step-map" that shows
location in the overall data entry process.
If you really want to be aggresive, consider also allowing automatic save
of the current state so that the user can always pick up where they left
off on new sessions.

50 fields in a form??? Me thinks the bug is in the design.
Cheers!

I had a form with lots of custom tags. When run under the Sun 1.3 JDK it
was
slow as molasses. Sun 1.2 JDK or IBM 1.3 was instantaneous. A few mailing
list posts pointed me to a bug in Sun's 1.3 having to do with nested
try/catch blocks in the compiled JSP.
Try your page under Sun 1.2 or the IBM JDK and see if it makes a
difference.

My form does not have a lot of tag processing (acutally none) The time it
takes to load the page is proportional to the number of instances of form
objects appeared on the JSP.
For instance, outputting a radio set is A LOT slower than outputting a drop
down list since you just have to pass a collection to the "iterate", but
you
have to actually put all the <html:radio/> options on the JSP.
<html:select property="factors[4].rating">
<html:options collection="ratings" property="value" labelProperty="label"/>
</html:select>
<html:radio ...../>Option A
<html:radio ...../>Option A
<html:radio ...../>Option A
<html:radio ...../>Option A

I have had the same problem on one very large form with lots of back end
tag
processing. Would be interested to know if anyone had performed any
profiling on similar situations to identify where the bottlenecks were.

made it a little bit faster when I converted all radio button sets to drop
down list, still it is very slow. The speed to load up seems to
exponentially related to the number of form fields.
