Re: [Evolution] Evolution performance

[Reid Vail <rsv869 roadrunner com>]

Hello Adam -

Thanks for the advise.  

Answering your earlier question, yes there is about 500meg, I think,  in local mail (inbox) and at least that 
much more in folders.  The Inbox is of course under "On this computer", but so are all of the folders.  I'm 
not sure if that's part of the problem or not.

I can't tell for sure if 3.6.4 is mbox or maildir.  I've looked for documentation and haven't been able to 
figure that out yet.  I think it's maildir.  And I'm honestly not sure what the steps would be to migrate 
from mbox to maildir.

I have tried a few of your suggestions; purging the .cashe and also emptying the trash but there didn't 
appear to be performance impact.

I did try a different tack; I installed Mint17 on Vituralbox, installed Evolution (rev 3.10.4, migrated my 
wife's mail data to that and saw a big improvement.  But there are major differences in her architecture and 
mine.  I have much faster CPU and a SSD drive.  So, I think my plan is this.... get her on a an upgraded OS, 
install the new Evolution and see if that helps.  If not, put in an SSD, and then upgrade the CPU if needed.  
Does that make sense?

Thanks

Reid
