[Bug 353449] Re: lyx 1.6.x impossibly slow
For what is worth, the new update mechanism has been ported to LyX 2.3.1. Currently, this is only available on Disco, which has LyX 2.3.2. It is of course available through the ppa for older versions.

[Bug 353449] Re: lyx 1.6.x impossibly slow
I just changed from the proprietary ATI driver to Radeon (as a result of switching to kernel 3.16) and this bug now affects me. I'm pretty sure its the driver. I'm also using compiz. Not sure why LyX is so slow when other apps aren't, but a multi-Ghz machine should be able to keep up with how fast I can type. Isn't it funny how hardware is at a blazing speed, but the useable speed is roughly the same as a few decades ago. Infact, I think my Atari ST could open windows faster than my Ubuntu box. Possible Workaround. If using Compiz, load ccsm and see if the Copy To Texture plugin is on. If so, see if turning it off helps. It seems to work for me. I'm wondering if LyX isn't reporting what part of the screen was damaged properly or something like that and its causing compiz to copy the whole window to the texture instead of just the damaged area. This would explain why a smaller window helps. I'm betting the bug only recently hit me either because the fglrx driver has a hardware speed-up for copy to texture or because I didn't have the Copy turned on before (I had to reconfigure a few things when I switched).

Re: [Bug 353449] Re: lyx 1.6.x impossibly slow
This is incredibly weird. I added the line to preferences ... If I start with Copy To Textures off, its OK an I can turn Copy To Preferences back on while Lyx is running and it looks like the preferences line has fixed things. It looks very quick like this. I then turned Copy To Texture back off, as it was when I started it. Its worse than ever! I turn copy to texture back on, and its back to being slow (like before any of this started). Turning off Copy to Texture fixes it again. If I start with Copy to Textures on, it looks like the preferences change has fixed it. I turn Copy To Textures off, and now its so slow that it misses keystrokes (see Bug #1329082 ) - a bug I haven't been able to replicate, but can do so following these steps. LyX now has to be closed. You can't use it no matter what I do to CopyTo Textures. Removed added preferences line ... I started with Copy To Texture off. Slow. Turning it on now invokes Bug #1329082! Its like keys are getting stuck in the event buffer. Old keys come out that were missed when typing new ones. Very strange. Restart with Copy ToTexture on. Fast. Turning it off. Still Fast. Back on. Still fast - nope - gave it a minute ... slow again. Turning off copy to texture fixed it. Apparently, the preferences change has some effect on this, Copy to Textures has a dramatic effect - both at the time LyX is started and the current state, and how long your using it. Its at least 4 different factors. I'll keep playing with this later. Any ideas on specific tests you'd like me to try? Its hurting my brain!

Re: [Bug 353449] Re: lyx 1.6.x impossibly slow
Sometimes doing things that no sane person would do gives insights. Othertimes, it just hurts more. For some odd reason, it seems to be behaving exactly the opposite of how it was behaving initially as far as Copy To Texture, but maybe I had it in a different state when LyX started up. The following tests were done by setting the given settings, loading LyX, opening a 100+ page document, scrolling up and down a bit, and then starting a new paragraph and banging away like a mad monkey and seeing how well it keeps up. I also looked at scroll speed and ended by typing a sentence to see if it was in a losing keystrokes state. If it couldn't keep up, it was marked Slow, if it kept up, it is Fast. Sometimes, the performance would change and get slower or faster, and I tested everything again when this happened. Sometimes it would get to the point where it would lose keystrokes - it actually looked like some sort of buffer overflow. Once it loses a keystroke, you have to hit a key to get the one it lost. I marked Bug #1329082 https://bugs.launchpad.net/bugs/1329082 as a duplicate as this is definately what I was seeing before. I'm 80% sure these problems don't appear on the binary ATI driver, but I'm not willing to re-install it to find out just yet. Getting rid of it was like pulling teeth.

Re: [Bug 353449] Re: lyx 1.6.x impossibly slow
Honestly, I have no idea what Copy To Texture was set to before I killed the proprietary driver. I could never see a difference turning it on before. But, trying to get rid of the driver lost OpenGL until I fixed it, and that made Compiz turn off half a dozen plugins. So - who knows how things worked before. I have no problem leaving it on. I think its slower to have on if you are low on RAM maybe - and I have 8GB - 7.2GB after the on-board video (its a laptop) steals some, or maybe its a software workaround for texture-size limitations? I dunno. Of course, the next guy may get totally different performance with these settings :) It may not be as fast as the proprietary drivers, but its close enough.

Re: [Bug 353449] Re: lyx 1.6.x impossibly slow
I managed to get the bug back - not sure why its intermittent. I've been playing with it for hours and if I bang away like a mad monkey for 5 or 6 lines, then it enters an extra-slow mode where it misses keypresses. I'm guessing some sort of race condition. Its easier to trigger when the system is busiest and acting slow. But Copy To Texture is still the best bet. It seemed like setting graphicssystem to raster made things worse.

[Bug 353449] Re: lyx 1.6.x impossibly slow
In the meantime I've switched to a new machine (Core i) and Lyx 2.0.0 final on Debian. CPU usage of one core (of four) still rockets up when scrolling/writing in a large LyX window, but it's smooth enough and works without big lags. So for me this is solved, I'm afraid I'm not going to debug my previous situation any further.

I would propose to recompile with --enable-build-type=prof, compile, and then run LyX under a profiler like sysprof. This should show what is the process that uses all the time.

[Bug 353449] Re: lyx 1.6.x impossibly slow
After compiling and running the latest LyX 2.0 RC1, the problem still persists. My minimise workaround got a bit more tedious (having to retry a few times). The lag (with maxed out CPU usage) happens when both scrolling and writing (but not when opening menus) and depends on the window size. For tiny windows, it's nearly imperceptible, full screen windows are unusably slow. Thus it might have something to do with redrawing. The maximum lag free (yet with 80%-100% CPU usage) size with Evince minimised is about 600x600, with Evince right besides LyX roughly 250x250. My current paper is relatively straightforward: paragraphs with lots of math formulas. Every other document I tried exhibits the same behaviour. However, after turning off Compiz, everything went smoothly, without a single lag. Since I really don't want to miss Compiz' usability extensions, I hoped to find some config settings (direct output, syncing, ...) to improve the situation. Fiddling around in CCSM and nvidia-settings was fruitless so far. Turning on Metacity's compositing feature (without Compiz) reintroduced the lag. I tried recompiling with ./configure --enable-debug ... but what is supposed to be done then? Currenly my best bet is using LyX in a 600x600 window and applying the minimise-Evince workaround, which isn't exactly enjoyable, but more acceptable than turning off Compiz. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/353449 Title: lyx 1.6.x impossibly slow -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 353449] Re: lyx 1.6.x impossibly slow
The easiest way to deal with this problem is to divide your work into several parts. For example if you write a thesis, you can divide your work into several chapters. You just create a master lyx document and you can put there only the title of all chapters. For the detail of each chapter you create separate lyx documents and insert each of them using Insert-File-Child Document. By using this way, even if you put your bibliography in the master document. You can still access the references from each child document. The only requirement is you must open you child document from the master.

I am using lyx 1.6.2 on Jaunty and have extreme typing delay when working on my large project report (currently ~40 pages long). It's straightforward to type more than four or five words ahead of what is displayed on screen and this causes lyx to grey out while it catches up.
