113334 - Examine amount of painting during message display

Status: RESOLVED INVALID

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Scott MacGregor]

Using a stand alone message window, I turned on paint dumping to see how many
paints we try to do when displaying a message. I used a stand alone message in
order to rule out any folder pane or outliner painting. 

Displaying our standard test message causes 7 paints to happen. I then tried to
figure out how many paints are going towards the XUL header overlay vs. the HTML
body. To do that, I removed the header overlay broadcasting so only the message
body was displayed. I still saw 7 paints. This means all of the painting is
being caused by loading the body into the iframe. 

I wonder if the format of the HTML we are giving the parser triggers excessive
painting or if 7 is a reasonable # of paints for my example document.

marking dependent on the mail perf bug.

adding a plus in case you still think we need to look at this.

moving to 1.2 since message display perf investigation will be put on hold for a
while.  You can move this back if you think this needs to be fixed.

Scott thinks "too old to be relevant", so closing INVALID. Please reopen if you think otherwise.
