78071 - Submission of forms is very slow[form sub]

Status: VERIFIED FIXED

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

Description

[Johannes Fitz]

When I submit forms with many input-fields it is very slow (I have tried it on a
PC with an P3, 733MHz, 320MB RAM, Windows NT4, SP5 nad on a PC with P3, 500MHz,
224MB RAM, Windows 2000). I used Mozilla 0.81 for the tests.
Microsoft IE 5.x and 6.0 beta is much faster than Mozilla.

It's not a bug, but I think when it's possible to improve that speed the users
would be thankful.

PS: I have tried it with our Web-Application. If you need more information
please contact me (by mail).

I'll investigate and try to address this along with the form submit rewrite.

Comment 3

[Johannes Fitz]

Attachment: This is one of the form where mozilla is quite slow to submit it. When submitting the form some JAvaScript verification is done, the i send it to a servlet and this servlet calls some jsp's after storing the form. .

Johannes, can you include more of this testcase?  This is only the html file and
doesn't include the javascript files needed to submit the form.  When I click on
the (what should be) buttons that submit the order, nothing happens, and I can't
tell what should happend without the javascript.

Guesses: could be slow javascript being run, or the layout of the response page
returned by the server might be slow.  I'm guessing the bottleneck is not the
actual submission of the form per se...

Thanks!

Doesn't look like this is getting fixed before the freeze tonight.
Pushing out a milestone.  Please correct if I'm mistaken.

Comment 6

[Johannes Fitz]

I have tested the page I mentioned before again with Mozilla 0.9.2.
With this version the page is already much faster to submit than in 
Version 0.8.1 (The first time I needed about 16 - 20 sec. With the actual 
version 0.9.2 it's about 7 sec).

That's still a bit slower than IE (4 - 5 sec.), but I think it should be okay.

Moving target to mozilla1.0 based on [e-mail]  comment.

Comment 8

[Kevin McCluskey (gone)]

Bulk reassigning form bugs to Alex

Comment 9

[Asa Dotzler [:asa]]

Bugs targeted at mozilla1.0 without the mozilla1.0 keyword moved to mozilla1.0.1 
(you can query for this string to delete spam or retrieve the list of bugs I've 
moved)

This seems fine for me now - on WinNT v4 SP6 with 0.9.6. 0.9.5 was slow for me
on form sumbitting, same platform. Not tested on any other platform though.

johannes:

can you test in your test environment please? thanks a lot!

Hi!
 
I've just tested it on our test environment and in my opinion the speed is good
enough. It's still a little slower than with IE5.5, but I think you will never
get this.
 
Some test results (Used IE 5.5, Mozilla 0.9.6)
1) IE: ~9 sec.
   M : ~11 sec.
2) IE: ~7 sec.
   M : ~7 sec.
3) IE: <2 sec.
   M : >3 sec.
 
Sorry, but i can't explain my test environment ...

I think that this is still a performance issue. AFAIK there will be some
performance boosts in the future be cause some of the important goals for 1.0
are perfomance and mem-footprint though. Let's hope for the best. I will see if
I can 
test in my test environment with the given testcase.

This bug seems to be back to where it was in 0.9.5 for me (0.9.7 on WinNT 4
SP6). As I said above, 0.9.6 seemed as fast as MSIE for form submission.

Comment 14

[John Keiser (jkeiser)]

Big helpful performance gains should occur with bug 120682.  Let's test 'er at
that point.

Comment 15

[John Keiser (jkeiser)]

Hmm, how do you submit that form?  There's no submit button and every button I
click on just goes back to "#".

Comment 16

[John Keiser (jkeiser)]

That testcase is just broken ... could you please post a working one?  I'd be
happy to run it against the new bug 120682 patch.

Attachment: Test case

See new minimal test case for this bug.

Comment 18

[John Keiser (jkeiser)]

Ronny, what does that testcase do for you?  For me, both before and after the
checkin, it submits pretty quickly.

Comment 19

[Ronny Adsetts]

Re. #18

I click the form submission button, then approx. 15sec later the form actually
submits. During this time, all other browser windows do not respond.

Comment 20

[John Keiser (jkeiser)]

Hmm, strange, I can't imagine why that one-field form would take that long on
any computer.  What kind of computer do you have?

And can you try today's build?  Now that bug 120682 is fixed, form sub speed
should be a lot better.  I don't see why it would be 15s better, but here's
hoping :)

Comment 21

[Ronny Adsetts]

Computer is PIII/833 with 320MB RAM. Not sluggish :¬)

Anyway, the build from 2002-02-17 works as expected - form submission is snappy.
Let's hope this one is buried.

Comment 22

[Ronny Adsetts]

Hmmm... Strange. When I'd uninstalled the daily build above, and re-installed
0.9.8, form submission is fine though not as fast as the 2002-02-17 daily.

Very Weird. Maybe something in my profile was borked, though I did create a new
profile earlier today with 0.9.8 and it was still slow. I'm stumped now...
that's really thrown a spanne

Comment 23

[John Keiser (jkeiser)]

I'm thinking it's buried.  Thanks!  (Sometimes having an old profile does have
odd effects.)
