Hello,
I've routinely experienced in recent weeks that the evolution process on
my system is using more than 600 MiB of RAM according to the system
monitor application in Ubuntu. Why is this so? Is this normal for others
using evolution?
That would depend on what you're measuring. If it's 600MB exclusively in
Evo, it sounds high. If it includes shared libraries from Gnome, not so
much.
How can I find out? I'm just looking at the System Monitor GUI in Ubuntu
and sorting by Memory.
"ps -ely|less" and look for the RSS column. That's the Resident Set
Size, i.e. the amount of physical memory actually being used (in kb).
Note that some of that will also belong to shared libraries so it's not
an exact measure, but it should give a rough idea.
You can also do "sudo cat /proc/<PID>/status", where <PID> is the
process id of evolution (use ps to discover it). That will give a more
detailed view of the memory layout. See "man proc" for more info.
Do you see the memory usage growing significantly over time?
Yes. It seems to start out using ~24MB the of the course of 24 to 48
hrs, it increases to over 600.
If you mean 24MB after loading the active mail accounts, that could be a
memory leak, which would indicate a bug. I'm not an Evo devel so you'd
need to report it Bugzilla to get better feedback.
I have Evo running constantly on its own desktop and currently it uses
about 270MB resident memory.
That seems like a lot to me, but then again I honestly don't know what
evolution is doing beyond retrieving my email and storing contact
information.
It's all relative. At one time in the past 270MB would have been a huge
amount of memory. Now I get Firefox processes using more than that.
Right now I have a Chrome browser using over 280MB and Chrome is
regarded as fast and lightweight :-) I also have 4GB RAM on my system
(and it's 64-bit, which also affects memory usage). The real question is
whether it grows inexorably over time.
I'm not sure how to diagnose this issue. I found a mailing list thread
thread from 2002 in a search for "evolution email memory" online. [1] It
seemed to be related to my experience. I also subscribe to a number of
mailing lists via IMAP and sort each list to its own folder. I use
fastmail.fm for my mail server and use their email filtering to sort
mail before I access it locally through evolution. There was some
discussion on the thread about vfolders that I did not understand. What
is a vFolder? I couldn't tell you if I was using one or not.
A vFolder is a search folder, i.e. a view of one of more other folders
defined by a search expression (similar to a filter). It's not physical
-- you won't see it on your IMAP server for example -- but it's an
important part of Evo since both Trash and Junk are vFolders, not to
mention any you define yourself.
I don't use the trash or junk folders. I expunge deleted mail almost
immediately. And I use the Fastmail.fm's spam filtering that moves
flagged mail to a "spam" IMAP folder. Is there a way to remove these
vfolders?
You actually do use Trash even if you don't think you do. It's used
every time you move a message from one (real) folder to another (e.g.
using filters). Since IMAP has no "move" operation, this is done by
copying and deleting, and deletion uses Trash. Note that this means you
should expunge regularly after doing moves, if you want to recover
space.
In fact even if you expunge immediately, the message will still be in
Trash even if only transiently. You can't avoid using Trash. You might
be able to delete Junk if you turn off Junk controls completely, I don't
know. However I doubt that this is the source of your problem.
I've deleted a search folder that I don't remember making but I'm not
able to delete an "Unmatched" search folder that I never really noticed
before. How can I delete it?
It's built-in. I don't know that you can delete it.
