9490 - [PP] Mac - display folder list and folder contents is worst than M7

Status: VERIFIED FIXED

(MailNews Core :: Backend, defect, P3)

Description

[pmock]

Build Date & Platform Found:
 Mac Seamonkey commercial build 1999070810 installed on PPC 9600/300 OS 8.5.1

Overview Description:
 Double clicking on the server icon to expand folder/newsgroup list is slower
than M7.  Running on a 300 mhz machine with 144MB of ram, I literally have to
wait after a double click to before I see my POP, IMAP, or Newsgroups.  Sorry, I
don't have number to tell how slow.  It behaves slow enough to give the user the
impression that his double click did not happen.  There were many times were you
double click again then eventually it expands but it collapses again b/c I
mistakely double clicked again.

 Another example, after you have expanded the mail folder (IMAP/POP), there is a
long delay when you click on the Inbox folder before it will highlight the Inbox
folder and display messages in the Thread pane.

Steps to reproduce:
1) Start Apprunner
2) Launch Messenger using the Task or Component bar
3) Double click on the POP/IMAP server icon to expand the folder list
4) Wait.  Notice how long before it takes to display your mail folders

5) Select a folder (such as the Inbox that contains <20 messages)
6) Wait.  Notice how long before it takes before the Inbox is highlighted and
messages show up in the Thread pane.

Actual Results:
  A noticable delay before the folder are displayed or selecting a folder to
display its contents

Expected results:
  It should not be worst than Communicator 4.x

Additional Information:
 (Personal note: my 300 mhz PPC feels like a 100 mhz)

Actually, I would expect it to be worse than 4.x ....!  On the other hand,
showing messages in the thread pane should be a lot faster.  Try it with more
than 20 messages, there should be a noticeable difference.

reassigning to me.

I now have over 60 messages in my POP Inbox.  I don't see that much of a speed
improvement.  When I initially select the Inbox, there is still a noticable pause
before messages will display and the messages slowly populate.  I can see the
scoll bar moving to indicate more messages being added.

Personally, I like to keep as few messages in my Inbox as I can.

fyi - under IMAP, the performance is noticeably better displaying messages in the
thread pane.  There is still a problem with performance under IMAP trying select
another folder.  There is a pause after you click on another folder before it
highlight the folder.

fyi

Comparing the performance on my windows machine Gateway P200 with 64MB running

Win98 vs. my PPC 9600/300 with 144MB (vm off) in recents M8 optimized build, I

can say my windows machine run apprunner faster than my PPC.  It's very painful

to test apprunner on the Mac.

Do you think we could bump the priority up and maybe set the target milstone to

M9?  I believe Mac users will get frustrated.  (Personally, I would wait until

this issue is resolved before using it at home).

I can't do anything about the speed until some changes from RDF happen.  Those
changes are scheduled to happen in M10, although there is a possibility they
could happen earlier.

Thank you Scott for the explaination.  It helps me understand why.

Comment 7

[scottputterman]

I should point out that I'm not sure why it would be worse than M7.  I did add a
couple of more columns which might be making the difference.  I don't suppose
you have any data showing the speed difference between M7 and M8?  I'd be
curious as to how far apart they are.

Scott,



I compared using POP using the M7 (6-21-15-M7) with yesterday M8 (7-14-16-M8)

commercial builds.  I used a stop watch to time my numbers.  Under M8, the time

would vary expanding and collapsing the list of folder but the time always took

at list 20 seconds.



Under M7

To expand the list of pop folders, it took 1-2 seconds

To select and display the pop inbox containing 31 messages, it took 1-2 seconds

To collapse the list of pop folders, it took 1-2 seconds



Under M8,

To expand the list of pop folders, it took 27-47 seconds

To select and display the pop inbox containing 31 messages, it took 10-12 seconds

To collapse the list of pop folders, it took over 60 seconds at times.



You are more than welcome to stop by and use my PPC.  Ninoschka has a similar

machine that displays this performance problem.  It's very painful to test on the

Mac.

Putting on [PP] radar.

Sounds like this needs to be fixed for PR1, so I added a note to the Status
Whiteboard

[scottputterman]

changing to M11, though my Mac doesn't really feel too different than my other
machines.

Comment 12

[Phil Peterson]

loading folders is much faster in recent M11 builds. marking fixed.

Comment 13

[pmock]

Compared the performance between M7 and M11.  The performance is acceptable.
Verified as fixed.
