[Dx-packages] [Bug 968533] Re: Alt-tab to Firefox sends Firefox to 100% CPU; unity-panel-service to 80% CPU and hud-service to 20-80% CPU

@pieleric: I confirm it has gotten worse in 13.10. The BookmarkMenuHider didn't do anything for me, probably because most of my bookmarks are sorted and thus still in the menu. after installing the addon. The ui.use_unity_menubar trick did it, but I agree it is a pity it also disables HUD completely. Ideally the bookmarks should not be exposed to HUD, as they are already accessible through Firefox address bar (Ctrl+L). @holocronweaver: this looks essentially like the same bug, why create a new one that is going to be closed as duplicate? -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

Same problem here, though it seems it have worsen recently on 13.10 (with Firefox 25?). With 5000 bookmarks, hud-service uses one CPU at 100% all the time, with a complete freeze every-time I switch a tab or firefox's window gets the focus. By using the BookmarkMenuHider add-on to remove the bookmarks from the menu, the CPU usage goes back to 20% the time. This can be a nice workaround for computers with relatively beefy processors. You can find the add-on there: https://addons.mozilla.org/en-US/firefox/addon/bookmarkmenuhider Finally, the ui.use_unity_menubar = false fix drops the CPU usage of hud-service below 1%, and Firefox experience is back to butter smooth :-) Of course the drawback is that the menu is gone from the HUD :-( -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

[Dx-packages] [Bug 968533] Re: Alt-tab to Firefox sends Firefox to 100% CPU; unity-panel-service to 80% CPU and hud-service to 20-80% CPU
Hi, I'm using Firefox and suffered from often occasional lockups of system due to overload of both CPU cores by 2 unity-panel-service processes and hud-service. Especially often this behavior vere triggered when I tried to type a text on any forum (and that as extremely annoying). That happened pretty much often like every hour and sometimes a few times in a row. I think I found the reason why it happened to me and finally fixed it. Apperently I had ~30 RSS feeds in the bookmars menu + Feed Sidebar addon which caused them to reload every hour (not all at once but all during each hour). So, as result structure of the menu were changed every now and then. And these changes sometimes caused Unity Panel and HUD to overload system! So, to fix this issue I had moved all my RSS feeds and dynamic bookmars into Unsorted Bookmarks section which does not shows up on the menu (it's actually there but only as a link to open a bookmarks manager). Seems like occasional freezes disappeared from that moment. It's understandable that dynamic changes in the menu could require some resources but I'm pretty much sure that hoggin 100% of 64 bit dual-core CPU during 10-30 seconds is pretty much odd thing to do. At least I don't need these RSS feeds in the bookmarks menu but what will have to do those with RSS feeds on the bookmarks toolbar? Moving such feeds into Unsorted Bookmarks will totally break their workflow. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

@paultait22 I agree that the problems are almost certainly related, but for bug fixing it is important to clarify what version resulted in what variation of the bug so that devs can look at the changes between versions and figure out where things went from bad to worse. Most developers don't have time to read the comments and aggregate all the knowledge they contain. Typically they read the initial bug report, briefly scan the comments for clues, then declare the bug fixed as long as the initial problem is solved. Since your problem has one additional condition, it is worth making a separate bug report that ALSO mentions this bug report.

@jdstrand Unfortunately on 13.04 this change did not affect Firefox cpu usage. Please create a separate bug report for the issue as I don't want to deal with it once I upgrade. =) -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

The problem may be more difficult. The high load - when switching between apps with Alt-Tab appears randomly. The amount of FF bookmarks in my case is high but do not changing much. Most time I have no problems while running FF and switching to another apps - windows with Alt-Tab. But sometimes happens, that high load (100% on both cores - for many seconds) occurs and stays until I kill FF and log out-in. If it would be caused by bookmarks - then it should happen all time - the same way. Not just occasionally. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

@radiobuzzer Lately the unity menu integration does not come as an addon. So, the previous solution (to disable the globalmenu addon if ones has high CPU load) does not work. The addon, Unity Desktop Integration, is still present in Ubuntu 13.04, and probably will continue to be in some form for the foreseeable future. Without a Firefox addon Unity has no means of using a simple API to access the bookmarks, so it is highly unlikely the addon will be replaced with some non-addon based interface. Perhaps you manually removed the addon via the package manager? -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

[Dx-packages] [Bug 968533] Re: Alt-tab to Firefox sends Firefox to 100% CPU; unity-panel-service to 80% CPU and hud-service to 20-80% CPU
The issue has a misleading title. The issue occurs generally when hitting the ALT key. I confirmed with Firefox 23 on Ubuntu 12.10. Lately the unity menu integration does not come as an addon. So, the previous solution (to disable the globalmenu addon if ones has high CPU load) does not work. I found another solution, which is not optimal, but solves the problem to a certain usable extent. The problem was that there were hundreds of bookmarks in the bookmarks menu and the bookmarks toolbar. Some of them were dynamic RSS bookmarks, which means that they kept growing by the time. So HUD had to index all these bookmarks. The solution was to move all the useless bookmarks from the bookmarks menu to the unsorted bookmarks. The latter do not appear in the menu and therefore do not have to be indexed by HUD. After I did this, still HUD requires a little bit of loading, but it is much faster and, most important, does not halt the entire system. I still believe there is an issue with HUD here: the entire adventure with the hundred features indicates to me that HUD's indexing is sub- optimal: it keeps re-indexing the same things that have already been indexed before, probably there is no (sufficient) caching or so. Another possibility could be a limit on the number of the bookmark items being indexed by HUD. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.
