Summary:  We need to improve mailnews footprint and performance.

The big areas are:

1) reply, compose
2) message display
3) folder loading
4) startup
5) addressbook

Details:

issue	bug #	owner
new compose window (using a cached window)  [not on by default.  to try it, add user_pref("mail.compose.max_recycled_windows", 1); to your prefs.js]	104989, 109081	ducarroz
msg reply (using a cached window)	104989	ducarroz
investigate reply speed, after # 104989		ducarroz
fix first compose window speed, after # 104989 (with turbo, and without)		ducarroz,varada
improve reply to imap message with attachments (only quote the body)	101480	cavin
investigate fcc2 menu in compose (should be done lazily)		cavin,varada
switch from tree to listbox in the addressing widget	70858	hewitt
remove "composeSaveMenuItems" command set	98657	sspitzer
reduce composer toolbar updating (blur problems, like in  107481 ?)	108038	sspitzer
reduce composer toolbar updating even more, if we can focusedElement wasn't null when editor has focus (or figure something else)		sspitzer
hack, or use setTimeout() to improve tabbing from address to address, address to subject, subject to body	108393	sspitzer
investigate message display ( selectively notify hdr sink, cross xpconnect as few times as possible when notifying header sink, create browser XBL widget w/o session and global history)	108635 , 22960	mscott
investigate and improve CollectAddress() perf	109107	mscott, sspitzer
downloading parts more than once during display?  (imap),  needs investigation.	93208	bienvenu
de-orkinizing and xpcomization of mork	110850	bienvenu
investigate folder loading		cavin,naving,bienvenu
investigate mork		bienvenu
investigate footprint (where's the memory going?)		naving,bienvenu
investigate leaks		bienvenu,naving
reduce mail-toolbar updating [improvements made]	107481	cavin,sspitzer
fix "n" navigation performance ( ignore duplicate .msf files)	104610	naving, neil
local mail perf problems with a large folder folder (cache mailbox:// connections)	104676	naving
open local mailbox file in read only mode, when possible	108276	naving
imagelib caching (affects menus, and addressbook)	106817	pavlov
find better value for nsXULAttributeValue::kMaxAtomValueLength	104905	sspitzer,waterson,alecf
i18n issues	103451	nhotta,cavin
investigate startup time (creating 4 web shells, cavin investigating)	26455 , 7251	cavin
don't do news on startup	103010	sspitzer
investigate how expensive our folder datasource usage is in the folder pane		sspitzer, cavin
investigate our account manager datasource & folder datasource based XUL template generated content (get messages, copy, file, move).  should all be done lazily.  (startup perf, general perf, footprint)	68375	sspitzer, cavin, neil
investigate other XUL template generated content (charset menu, tasks, etc).  should all be done lazily		cavin
investigate a simpler skin (does modern's complexity and polish slow us down?)		hewitt,sspitzer
investigate time to delete message and load next message since that's such a common operation (toolbar flashing on delete, selection goes from 0 to 1 to 0) [improvements made]	100802	bienvenu
switch it so that we display the contents of the imap folder before we connect to the server and do folder discovery and download headers.  (though you can't load a message until we've finished all that.  we might want to investigate doing folder discovery on a different thread, though it could cause problems)		bienvenu
Preferences UI bloats and seems to leak	107709	bienvenu
reduce number of mork tables we create when loading a folder	111976	bienvenu
Reduce number of outliner row repaints and speed up painting	112253	bienvenu
updating total / unread too often when downloading imap folder first time	112761	bienvenu
cache most recent thread object asked for, should speed up painting of thread pane when in threaded mode	111976	bienvenu
switch to using PRPackedBool	108584	sspitzer
convert some PRInt32 / PRUint32 attributes to PRUint8 (priority, label, etc) in common objects like nsMsgDBHdr		sspitzer
ab:  investigate performance	107151	sspitzer
ab:  switch to pure outliner (not rdfliner) implement a nsIOutlinerView like we do in nsMsgDBView for the results pane, and ab sidebar (see http://www.sspitzer.org/ab.html )	73868	sspitzer
ab:  switch to rdfliner for addressbook / mailing list pane (like we do in the folder pane) [not going to do it, see hyatt's post to xpfe]		sspitzer
ab:  clean up directory and card datasources		sspitzer
ab:  clean up addressPane.css .	105835	sspitzer
cache edit / new card window, like in 104989		sspitzer
reduce allocation when painting in addressbook, like dmb did in thread pane.		sspitzer
ldap queries leak		sspitzer,dmose
improve LDAP performance		sspitzer, dmose
improve LDIF import performance		sspitzer
improve local AB performance		sspitzer
increase string bundle cache, break apart our string bundles (especially compose, move the errors out from the main compose bundle), make sure the string bundle cache is big enough that we aren't swapping out bundles, or make callers hold onto bundles where possible.	104988	sspitzer
batching for multiple msg delete	80897	naving
batching for other commands, like marking as read		sspitzer,naving
add const getters for path and spec to nsIURI, and use them. (may not be worth it.)	110797	cavin,sspitzer,darin
automate leak / bloat measuring, tie into tinderbox	108577	varada, stephend, mcafee
add better logging so that stephend can automate more of his timings	78787	varada, stephend
