Startup of Thunderbird with Lightning enabled has become extremely slow
User-Agent: Mozilla/5.0 (X11; Linux i686; rv:6.0a1) Gecko/20110511 Firefox/6.0a1 Build Identifier: Mozilla/5.0 (X11; Linux i686; rv:6.0a1) Gecko/20110511 Thunderbird/3.4a1pre Something in core has led to a major increase in time Thunderbird with Lightning takes to open. On my hardware 4 seconds with a 2011-05-10-14-comm-central nightly (c-c SourceStamp=11e51879e4f7) vs. approx. 20 seconds with my private build from c-c SourceStamp=a4209b15c186 with a clean new profile. Reproducible: Always Steps to Reproduce: 1. Build Thunderbird package from comm-central with --enable-calendar or use an official nightly build > 2011-05-10-14 once it becomes available 2. Extract the content of the package, run thunderbird 3. Install Lightning, restart Thunderbird Actual Results: Thunderbird takes abnormally long to open after Step 3. Expected Results: Startup time doesn't increase significantly, at least not much more than twice as without Lightning (Step 2). Testing platform: Ubuntu 10.10. If the fix must be in core and not in Lightning, I could try to bisect to find the offending commit.
Bisect done, the first "bad" commit is <http://hg.mozilla.org/mozilla-central/rev/bedef853b523> from Bug 513006.
Verified by local backout of <http://hg.mozilla.org/mozilla-central/rev/bedef853b523>. m-c revision: 427fa3603d4c+ c-c revision: a4209b15c186

The patch from Bug 513006 has been backed out for another reason <http://hg.mozilla.org/mozilla-central/rev/2b649bafb84a>, so marking this bug as fixed (verified by a local build).

I just upgraded from 184.108.40.206 to 8.0, 2011.12.08 and the performance is very slow. With nothing else running it took 21 seconds to start. Lightning is also an add-on. My experience does not support the statement that TB is faster. This is significantly slower that 220.127.116.11 Other issues will be reported separately. I would not consider this resolved or fixed in Windows. System Xp, Sp 3
