So there we are. I restored those mails, by removing last seen uid list from

martin at merkaba:~/.kde/share/config> ls akonadi_pop3_resource_*
akonadi_pop3_resource_0rc  akonadi_pop3_resource_2rc  
akonadi_pop3_resource_4rc  akonadi_pop3_resource_6rc
akonadi_pop3_resource_1rc  akonadi_pop3_resource_3rc  
akonadi_pop3_resource_5rc

And having it redownload stuff.

Due to the duplicate entries in the database and a scary message that 
resource Lichtvoll already exists, I have it redo the Akonadi and Nepomuk 
database while taking care to adjust inbox filters. I also re-imported filter 
list to make sure they have the right target folders. (I still think KMail 
should bail out with a LOUD error message if database ids have changed! But 
I at least I knew this pitfall already)

Now Akonadiconsole reports the Akonadi Nepomuk Feeder as "Nepomuk is not 
operational: Nepomuk is not running". I understand that I can fix that by 
restarting it. But for that I will wait till things have settled down.

Now actually I understand complaints about resource usage. Akonadi + Nepomuk 
occupied 2-4 logical cores of a quite high powerer Intel Sandybridge 
i5-2520M 2,5 GHz for more than day. And then this ThinkPad T520 let the cpu 
overspeed itself at upto 3,2 GHz for quite extended period of times. And it 
also occupied the the Intel SSD 320. I consider this hardware to still quite 
top-notch.

I wonder what my older ThinkPad T42 with Pentium M single core processor and 
slow 2,5 inch laptop harddisk would have done. I think Akonadi + Nepomuk 
would have made it unusable for at least a week to come.

For me, this is still showstopper. I think it will work on this high powered 
hardware. At least, if I, if need be, disable full text indexing, at least 
on certain folders.

I think there is room for improvement. Our Zimbra servers does MySQL for 
mail metadata and Lucene as search index with 40+ accounts on one machine 
and it never appeared that occupied with it for that extended periods of 
times. Well I do not have any hard scientific data, but still.

Anyway, I now try to have KMail remove duplicated mail due to the deletion 
of the last uid seen list. I think it settled down.

I think its mostly the full text indexing that consumes that much resources. 
Akonadi builds up a more than 1 GB database in about an hour or so, so the 
Akonadi sync seems to be pretty fast.
