106087 - msgmapi.dll, messenger chrome files loaded at browser startup

Status: RESOLVED WONTFIX

(SeaMonkey :: Startup & Profiles, defect)

Description

[Dimitrios]

On a total 9 sec of cold start time, we spend 0.36 sec for msgmapi.dll, 0.03 sec
for messenger\content\overlays.rdf and 0.061 sec for messenger.jar (see txt or
excel attachment in bug 7251). This is 5% of total time (maybe more, if there is
additional cpu activity because of compiling the data and memory allocations).
Couldn't these files be late loaded (when Messenger starts)?

re-assigning to Cavin, this may end up being a dup of bug 26455 though.

Stephen, I don't see how this is related to bug 26445 which is about mail
startup performance. Anyway, there are a few more things I forgot to report:
- mailnews.js is also loaded during browser startup (26 msec). Couldn't we load
it only when prefs ui is loaded?
- msgmapi.dll does exist on Win2K (and it's used during browser startup) but it
doesn't exist on Win98 installation (the installations are identical with full
pop account information). On the latter, FileMon reports a failed (not found) 
attempt to find msgmapi.dll. Also in your attachment I can't locate msgmapi.dll.
Did you use Win98?

Confirming.  Cavin or Chris, do you know of a bug on the browser said about
loading Mail dlls?

I know of an old bug about loading mail dll's (yes I know you asked a long time
ago...). Take a look at bug 12896. I also added a comment in the said bug
pointing at this one.

Any possible progress on this one, or should it go into the "WONTFIX" file?

msgmapi.dll does not exists on Vista. It does not appear on windows XP.
While TB2 still runs on win95 and win 98, TB3 as different system requirements (http://www.mozillamessaging.com/en-US/thunderbird/3.0b2/releasenotes/#requirements). TB2 being in maintainance mode - resolving this as WONTFIX

Well actually we used to ship msgmapi.dll, it got replaced by mozMapi32.dll

This is actually a SeaMonkey bug now (TB has now browser, so its definitely invalid for TB), and I can't decide if its something SeaMonkey needs/wants to look at or not - so moving to SeaMonkey and reopening for now.

Mark how about we close this as a dup of bug 119590 ?

The SeaMonkey team has no interest in fixing this - actually, we even check for mail on browser startup by default now.
