After reading more into the synchronous mode I found the mode NORMAL

When synchronous is NORMAL (1), the SQLite database engine will still
pause at the most critical moments, but less often than in FULL mode.
There is a very small (though non-zero) chance that a power failure at
just the wrong time could corrupt the database in NORMAL mode. But in
practice, you are more likely to suffer a catastrophic disk failure or
some other unrecoverable hardware fault.

This on gives me 
DEBUG:zeitgeist.engine:Inserted 1 events in 0.001519s

Bug description:
We insert pretty slowly with an average of 0.15 seconds for one event on my 
core i5 2.5 GHz beast.

RainCT had some optimization possibilities:
1) PRAGMA synchronous=OFF
2) PRAGMA journal_mode=OFF

The Chat:
------------------------------------------------------------
<kamstrup> I think we are - but I can't recall... in case of failed 
transactions - but I don't even know if we use transactions these days...
<seif> <RainCT> try synchronous=OFF
<seif> <RainCT> but it can corrupt your database if your phone dies while ZG is 
inserting
<seif> <RainCT> and journal_mode=MEMORY
<seif> <RainCT> or OFF since we don't use rollback anyway
<seif> so maybe journal_mode = OFF is a good start?
<kamstrup> okay, he's probably right...
<kamstrup> 'grep -Ri rollback _zeitgeist/' is your friend :-)
<kamstrup> apparently we are not using rollback...

In order to get a better picture of what's going on, can you please try to get 
some more information, like:
1) How many events are in your database?
2) What's the insertion time for one event into an empty db?
3) Out of this 0.15 secs, how many time is spend in our python code, and what's 
the time of the actual sql action?
4) How much faster is adding 10 events at once compared to adding them one at a 
time?
5) You think 0.15 secs is slow for inserting one event, what time do you 
expect, and why?
