Tested with fairly recent (2 days old) builds on Mac and Windows. - Create a text file with about 50 small lines of text. - Give the file a ".html" extension - Open the file in the Editor ==> It goes fast - Give the file a ".txt" extension - open the file in the Editor ==> It's slow (a couple of seconds) - Increase the size of the file to about 150 lines - Keep the ".txt" extension and open in the editor ==> It's incredibly slow (10-15 seconds on G4 and PC) - Rename the file with a ".html" extension - Open it in Navigator or in the Editor ==> It goes fast Conclusion: the Editor is VERY slow with ".txt" files compared to ".html" files and it seems to be exponentially slower as the size increases, even for files as small as 150 lines of text.

This is covered under 28783, but i'll leave it open in case there are some other performance issues.

M16

M17 for perf.

setting to m19

please do not nominate for nsbeta3 -- this will be addressed after crashes, regressions, correctness and polish bugs have been resolved, all Composer perf bugs have been set to m19/m20

moving out ot future, will concentrate on this type of work post rtm

Performance -> 0.9.1

-> 0.9.2

Does my latest patch in 74656, along with a good environment setting for $BLOCK_FRAME_LINE_CACHE_THRESHOLD (25?) help this problem at all? I'll do some testing when I resurrect my build, but I thought I'd throw it out. (Kudos to rbs for tipping me off to this bug.)

This bug really sucks now that we can load big plain text files. I'll try shaver's patches.

simon, any results here with the patches?

sorry, this needs to go over to 1.0

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)

removing myself from the cc list

Pre-sabbatical bug triage. ->jfrancis

The trunk is the wave of the future!

The days of having a half dozen milestones out in front of us to divide bugs between seem to be gone, though I dont know why. Lumping everything together as far out as I can. I'll pull back things that I am working on as I go.

migrating milestones now that there are more available. i'll pull these back as I work on them
