214908 - paste long text in a form is too slow

Status: RESOLVED INVALID

(Core :: DOM: Core & HTML, defect)

Description

[xspuente]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; ast-ES; rv:1.4) Gecko/20030624
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; ast-ES; rv:1.4) Gecko/20030624

When pasting long text (500,000 letters) in a form, Mozilla is too slow in
comparisson to other programs or browsers. It takes a couple of seconds, instead
of being inmediate or only 1 second. It has been reproducible from all major
releases till now.

Reproducible: Always

Steps to Reproduce:
1. Go to
http://genome.ucsc.edu/cgi-bin/hgc?hgsid=23574695&g=htcGetDna2&table=&o=1457976&l=1457976&r=1492610&getDnaPos=chr2%3A2000000-2500000&db=rn3&hgSeq.cdsExon=1&hgSeq.padding5=0&hgSeq.padding3=0&hgSeq.casing=upper&boolshad.hgSeq.maskRepeats=1&hgSeq.repMasking=lower&boolshad.hgSeq.revComp=1&submit=Get+DNA,
select all and copy.
2. Go to http://www.ncbi.nlm.nih.gov/blast/bl2seq/bl2.html, and paste in any of
the forms (called Sequence 1 or Sequence 2) 


Actual Results:  
It takes 16 secs

Expected Results:  
Take 1 sec or less, as in IE or any text editor.

There is a dependency on the text lenght, as it increases size it takes longer
to load. It might be the same in other browsers, but as it takes less than 1
sec, you don't feel the difference.

I too have experienced some inefficiency with Mozilla form handling.  I frequent
www.dapcentral.org where there are large form lists for video inventories (some
with a few hundred radio buttons).  While IE will submit even a large form such
as this almost instantly, Mozilla hangs momentarily while processing all the
data.  Not exactly priority one, but I agree it would be wise to have someone
look into making it more efficient.

I'm seeing this in Linux with 1.7rc1, but it was OK before. This seems to be
true when pasting anything, anywhere. It's now really slow. The bug seems to
happen most, but not all times when pasting.
