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.

Resolution: --- → FIXED
I just upgraded from 2.0.0.24 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 2.0.0.24

Other issues will be reported separately.  

I would not consider this resolved or fixed in Windows.
