Switched to PostgreSQL

[Martin Steigerwald]

Hi.

So after 2/3rd's of a day and letting it scan through the local maildir 
collection throughout the night, after at some point during the day I 
stopped akonadi_indexing_agent to accelerate the scanning process, I 
have my private KDEPIM/Akonadi setup on PostgreSQL.

So far the performance is really quite a bit better. The stalls during 
filtering are gone. About the crashes I am not sure yet. Also I found 
that there are no stalls anymore on deleting a mail.

So far it looks like this:

~/.local/share/akonadi> LANG=en du -sch *
4.0K    akonadi_control.error
4.0K    akonadi_control.error.old
12K     akonadiserver.error
3.1G    db_data
79M     file_db_data
1.3G    search_db
4.0K    socket-merkaba
4.4G    total


Did anyone with PostgreSQL setup did any tuning on the database?

I see that the various PostgreSQL processes do not take all that much 
RAM yet. They take quite a bit of RSS, but apparently share lots of it, 
so the PSS is quite a bit lower (see in atop, memory display with "m", 
enable PSIZE gathering with "R").

Is there something like mysqltuner for PostgreSQL? Otherwise I can use 
my own training slides or official documentation.

However, as long as it stays as fast as it currently is, I might just 
let the configuration alone for now.

Let's see how this goes.

Thanks again for the hint to switch to PostgreSQL and the instructions 
for how to do it.

Ciao,
