displaying the mails of a subfolder with about 770 mails need a long time (~30 secs)

Reproducible: Always

Steps to Reproduce:
Req: Have a subfolder with 780 old and a new mail.
1. Select the inbox
2. Select the subfolder 


Actual Results:  
After about 30 s the new mail appears 

Expected Results:  
Shouldn't need that long. (MAX 2 s)
Comment 1 Ludwig Reiter 2010-11-19 11:52:20 UTC 
Other test with about 2100 old mails shows that it needs 70 s to display the new mail the second time it is looked at. (The first time it needs about 5 mins or so.)

Hej,

I committed a couple of performance patches yesterday, can you retest with a current version, please?

Ciao,
Tobias

On maemo it took ~10-15 sec until a folder with 1000 mails was displayed. On Wince it took ~10 times longer to synchronize it.
Comment 4 Bernhard E. Reiter 2011-01-19 11:54:00 UTC 
Ludwig, Björn, can you comment on how long it takes to display (not sync)
a new email on CE. which I would think is the time it takes until I can see the new email that already is in the folder.

Is there s difference in INBOX and a subfolder as the title suggests?
Comment 5 Bjoern Ricks 2011-01-19 12:08:26 UTC 
Bernhard for a simple pain/text mail it took ~5sec until it was displayed completely. My last test to sync a big folder were without the sqlite improvements from Sascha and Andre. Retesting is on my list of todos.
Comment 6 Bernhard E. Reiter 2011-01-19 14:27:47 UTC 
Björn, where the 5 seconds on ce in a folder with many emails?
Comment 7 Bjoern Ricks 2011-01-19 15:53:41 UTC 
Syncing a folder with 1000 new mails is much faster now. It took less then 10s until the first mails were shown in the folder list.
Comment 8 Bjoern Ricks 2011-01-19 15:57:41 UTC 
Bernhard I did restest opening a simple pain/text message in a 1000 mail folder and it got the same result as before when opening a mail in my inbox with ~150 mails.
Comment 9 Bernhard E. Reiter 2011-01-20 14:50:16 UTC 
Needs a test for email, contact and calendars now.
Comment 10 Ludwig Reiter 2011-01-20 15:15:57 UTC 
Mail Touch (Windows CE) 2011-01-16

Test of the description with old 1000 mails and a new mail.
Needs 30-40 s for displaying the new mail.

So still reproducable.

Since there is no immediate solution priority moved down to normal.
