[Bug 225950] Re: [8.04] Drawing evolution window on screen very slow
Actually I am using it with the option LDM_DIRECTX = True. I guess it is a remote X issue.

[Bug 225950] Re: [8.04] Drawing evolution window on screen very slow
I don't have tracker running. I've also tried the same version (2.26) on openSUSE from their community repository and it has the same exact problem, so it seems to be an upstream problem? Ever since 8.04, Evolution has been exhibiting a slow performance over ssh. Since LTSP 5 runs over SSH, this is why this problem occurs in a LTSP setup. -- [8.04] Drawing evolution window on screen very slow https://bugs.launchpad.net/bugs/225950 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 225950] Re: [8.04] Drawing evolution window on screen very slow
While the problem still exists in Ubuntu 9.04, when previewing and reading emails, a new problem has arrised. When pressing the compose new email button, I literally wait 15 seconds for the composer window to open. This is now Evolution 2.26 and this is not just LTSP, but anytime when Evolution is forwarded over SSH. I tested it on a different PC using the command ssh -X u...@hostname 'evolution' and it yields the same result. What about Evolution changes when forwarded over SSH is a mystery to me. Nothing is printed when using the --debug option. Does anyone know of a different bug is is? Possibly a component that Evolution uses to draw the widgets having performance problems when forwarded over SSH? -- [8.04] Drawing evolution window on screen very slow https://bugs.launchpad.net/bugs/225950 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 225950] Re: [8.04] Drawing evolution window on screen very slow
This bug is very frustrating because we're still hanging onto our 7.10 installation that does not have this bug. It would be great to update to a LTS release, especially since we only have 6 more months of security support. Since Evolution is used by all of our clients, we can't make that jump until this is resolved. Does anyone at least have any ideas as to why only Evolution seems to be the only application affected? What has changed from libcairo2 package from 8.4 on? I kind of feel helpless since I'm not a programmer and can only give my experiences. -- [8.04] Drawing evolution window on screen very slow https://bugs.launchpad.net/bugs/225950 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 225950] Re: [8.04] Drawing evolution window on screen very slow
My original problem was scrolling through the list of emails either using the arrow keys or using the next and previous buttons in the tool bar. The updated libcairo2 package did seem to resolve that issue, especially with the previous and next buttons. But after further review and testing, I'd have to agree that, overall, the drawing and manipulation of graphics in Evolution is delayed and clunky. I admit that the libcairo2 update from hardy-proposed did help, at least with my problem, but it isn't the full solution. Once again, the problem is more apparent when using LTSP, but I do not believe it is related solely to LTSP, especially when the Gusty Evolution 2.12 installed on the same system works perfectly. Also, every email that I view displays "Formatting Message" which rarely showed up in previous versions. Even an email with a single line causes Evolution to display "Formatting Message". -- [8.04] Drawing evolution window on screen very slow https://bugs.launchpad.net/bugs/225950 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 225950] Re: [8.04] Drawing evolution window on screen very slow
Let me go back on what I said about the message display pane being a little slow, and clarify that it doesn't seem slow to me anymore. It seems to be just fine so I guess I was seeing things. Sorry about that and I didn't want to add to any confusion. The part about the multi- email delete and still displaying the last email deleted is certainly a bug and can be reproduced every time. -- [8.04] Drawing evolution window on screen very slow https://bugs.launchpad.net/bugs/225950 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 225950] Re: [8.04] Drawing evolution window on screen very slow
I was only explaining my experiences and, now with knowledge of the bug you mentioned above, maybe it explains why the Debian Evolution runs just like the Ubuntu version, because the libcairo2 package was consistent on my Ubuntu system and I only installed the Debian Evolution packages. Anyway, I only had a few minutes to test it, but it seems like that was the problem and it is so much more responsive, so thank you so much. I know there is some debate in the bug you mentioned about whether to keep the patch or not, but I say remove it since Evolution is a widely used program and it greatly increases the performance. I plan on testing it some more, and I encourage others to try upgrading from hardy-proposed and test it too so you can give your feed back before we mark this as fixed (just to be certain). Thank you so much for your help with this bug. Now if we can speed up the message reading pane in Evolution, because it seems like every message, no matter what the message, I get a half a second or more of "Formatting message", even if it's only a couple of lines in length. Does anyone else experience this, or maybe I'm just seeing things? And every time I delete a group of emails at one time, it doesn't hide the very last deleted email but remains listed and crossed out, even if I press Send/Receive. It's not until I change folders or somehow refresh the email list does it goes away. Know of any bugs filed for these two issues or should I file them myself? -- [8.04] Drawing evolution window on screen very slow https://bugs.launchpad.net/bugs/225950 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 225950] Re: [8.04] Drawing evolution window on screen very slow
Here's what I've observed from some crazy experiments. I've noticed that Evolution 2.22, regardless when using it on a normal Ubuntu install or on a LTSP thin client, it is more sluggish than the Evolution 2.12 found in Gusty, for the very same reasons stated above. It seems to take two seconds for Evolution to "Formating Message" where the previous version, the formating was instant. Scrolling from one email to the next is also very choppy, especially using the previous and next buttons in the tool bar. This is experienced on a variety of machines, all at different speeds and specs (and apparently many other users). To try and pin-point what the problem is, I tried a few combinations of installs and found mixed results. All of these tests were with thin clients. First I had a basic Ubuntu 8.04 and LTSP installed and the 8.04 Evolution packages installed by default which had poor performance. I then installed Gusty's Evolution packages 2.12 instead of Evolution 2.22 on the very same server and the performance was excellent. I then tried Debian Lenny's Evolution packages 2.22 on this server and found the problem still exists. I then tried a complete install of Debian Lenny's LTSP server and Evolution 2.22 and found the performance to be excellent (overall much quicker than Ubuntu's I might add). In summary: 8.04 LTSP + 8.04 Evo 2.22 = slow performance 8.04 LTSP + 7.10 Evo 2.12 = excellent performance 8.04 LTSP + Debian Evo 2.22 = slow performance Debian Lenny LTSP + Debian Evo 2.22 = excellent performance Based on these results, there is something about the Evolution 2.22 Ubuntu package that makes it a great deal sluggish than 2.12 in Gusty (the problem does NOT exist in Debian). When installing the 2.12 packages, I found no problem whatsoever so the problem seems to be with Evolution 2.22 and that the LTSP thin client model magnifies the problem a great deal. I hope this helps somewhat on where to look. -- [8.04] Drawing evolution window on screen very slow https://bugs.launchpad.net/bugs/225950 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evolution in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
