Re: [Evolution] About performance

Thank you Matthew.

This aleviated a little bit the situation. But not much. I still see 
something wrong. I have to investigate where the problems come from...





One known issue, especially for heavy users, is that fragmentation can
build up in the mail summary database over time, which does negatively
impact performance.  If you notice your hard disk grinding a lot while
working in Evolution, this might be the issue.

It might help to garbage collect the database.  Evolution does not
currently do that itself.  Try shutting down Evolution and run this
little shell script:

http://mbarnes.fedorapeople.org/evolution-rebuild-summarydb

Eventually I'd like to tie this into the Expunge operation, which seems
like a natural place for it to get run periodically.  Haven't done it
yet because, you know, time, manpower, priorities, etc.

Re: [Evolution] About performance

2013-05-22 Thread Contacto

Hi Pete,

Yes, I know that if I'm the only one reporting this it's surely a 
client/user misconfiguration. That's what I wanted to know before 
opening a bug.


But you cannot blame ubuntu or any other distribution for this.

The only reason that may affect performance in my setup is a lot of 
small things together:


1.- Big data folders in evolution.
2.- RAID setup on my home disk that's not optimal. In efect, I have 
to change it because it's really slow. That's because I did the raid 
with the BIOS support what's is an error. I know.

3.- Database handling in evo not optimal.
4.- memory leaks?


I want to setup right the point 2 but I want it to stay slow for a while 
to be sure it's not a matter of just put faster hardware. If 
thunderbird goes slow after a year I will write again and say: Hey, 
people, that was a normal issue because big folders and slow disks. But 
I don't think this will be the issue.


Anyway. Let's close this thread if nobody saw evolution go slower on 
time. Maybe it's only me.


Thank you a lot for your support!
Best reagards,

Because one person reporting problems is not usually credible - it's
indicative of a misconfiguration or an issue elsewhere.  Yes, it
sometimes is a problem, and given an infinite amount of resources all
such things would be investigated - but with limited (very limited)
resources, the developers have to concentrate on the things that have
the most impact for the most people.


The same occurs in evolution. Just because it works well for you it does
not mean it's  working well.

I can tell you that performance and usability degraded over time.

but not for most people.  My experience is that Evolution has become
more stable and more usable over the last few releases.  And yes, it has
become faster and more responsive.

To be honest most of the grouching about the stability and speed of Evo
seems to be coming from Ubuntu users - that may be because there are
just more users of Ubuntu than other distros; or it could be something
that the Ubuntu packagers have done to Evo; or it could be some
interaction of Evo with other libraries that Ubuntu have modified.
That's not to say that there aren't reported problems with other
distros, but they don't seem to make Evo unusable like it reportedly
does on Ubuntu.


If I'm taking my time explaining what's the problem I suppose that
someone should take some time in investigating what can be wrong. It's
not a waste of time because doing it will improve overall usabiliy of
all users.

I'm not blaming. I'm just warning about a problem that made me switch.

Hope you understand that I love the program and that's why I'm telling.
That's not blaming.


Please take time to analyze what I'm telling. I suppose that I'm not the
only one that suffered of this.

Have you filed bug reports in bugzilla about it?  That's the only way
that it's going to get into the developers list of things to look at -
the more people that file bugs, especially if they turn out to be the
same problem, the more likely that it will be looked at.



Note: My current version is: 3.6.4. And crashed while writing this on
Thunderbird. So I didn't touched anything when crashed.

If it crashes while doing nothing, then you really need to get a
backtrace on it with all the symbol packages installed so that someone
can see exactly where and why it is crashing.  Useful information on
doing this is at

   http://projects.gnome.org/evolution/bugs.shtml


I suppose it's a small bug. But this is not the problem. Problem is
performance.


File bugs about it.  That's the only way the developers can get a view
on systemic problems and can spot patterns.

It's also very helpful if when you do submit a bug following a posting
to this list, that you tell us the bug ID - at least then if some one
searches the list archives (because we ALL do that before posting, don't
we) they can at least see if the problem has been fixed, or can add a
comment to the bug.

Finally, the developers make advances and improvements and bug fixes in
the current version and only bug fixes in the previous version - so it
is always worthwhile running the most up to date version before
criticizing things too much.

P.

Please add in Ubuntu to your statements as you chose to use a
distribution that deliberately ships old versions and doesn't provide
upstream bugfix updates to their users.

Just to get the facts straight who to blame for missing quality.

This was true in the past but not now.  Ubuntu 13.04, which was released
in late April and is based on Gnome 3.6, provides Evolution 3.6.4,
released 6 March 2013.  Six or seven weeks later: pretty up-to-date.  If
you like Ubuntu and must have the 3.8 series you can go with Ubuntu
Gnome and update to Gnome 3.8; same as with openSUSE.  Now that Ubuntu
is a sorta-kinda rolling release, I expect more up-to-date versions of
everything to appear.

Evolution is no longer the default MUA in Ubuntu, but it still
integrates nicely with their version of the Gnome calendar.  Works very
well for me and my extended family.

Glad to see that at least developers use and test evolution in a day to 
day basis.


But man this is kind of the same problem of the known kernel IO problem 
that also I reported and nobody not much people trust just because they 
didn't see any problem.


When the kernel IO problem was noticeable for all the people it was way 
too late to find a solution.



The same occurs in evolution. Just because it works well for you it does 
not mean it's  working well.


I can tell you that performance and usability degraded over time.

Yes. It's a great e-mail client. One of the best. It supported even MS 
Exchange when no others did it. It supported IMAP as well. It has great 
plugins that made live easier and it used to work really well.


But performance problems right now are a serious issue.

If this were my product I will start profiling it. Just to see how 
fast/slow is and how can we improve.


I can say that I'm heavy user. I used to have thousands of e-mails in 6 
different IMAP accounts, and a lot of filters that classifies my e-mail 
in local folder when neccesary.


Well... Once the e-mail is classified it should not slow evolution. So I 
suppose this is not the problem.


So why the program is getting slower.

someone should take some time in investigating what can be wrong. It's
