Re: LyX Mac 1.4.0 Performance Issue

[Yaron Y. Goland]

This applies to top level text. The key seems to be how big the  
document is. I have an 8 page document with 12 equations and trying  
to type anywhere in that document (even if there are no equations  
visible on the screen) will peg my CPU and move so slowly I can type  
faster than it can handle.

Download Qt4.1.1 open source Trolltech tools. I can give a configure 
setup that will configure, make and make install the toolset. The 
performance improvements to LyX is quite noticeable.


Hello Marc,

You definitely caught my interest. Did you test the new qt4 frontend in 
SVN repository?
Please note that this is still experimental and not finished yet so not 
ready for the user. But, I am _very_ interested in your experience. May 
I suggest that you send a report to lyx-devel instead? We strongly need 
more MacOS X advanced testers and developers there.


Thanks in advance,
Abdel.

I think we have a proper patch for that.

Sorry - I have to take back my remark on the page-down issue below. I  
thought I saw that yesterday, but today that particular behavior  
hasn't happened again...  the delay in leaving math subscripts by  
cursor key is still observable, though.

Hi,

I can confirm this slowness. I installed LyX 1.4 from the binary  
installer on a MacBook Pro (Intel processor) so LyX is running in   
a processor emulation called Rosetta. This amplifies the  
sluggishness, which is bad for me but good for seeing directly  
where LyX is being slowed down. E.g., when I use arrow keys to move  
into a math formula, then I can press the down arrow multiple times  
until LyX finally moves out of the equation again. The buffered  
arrow key events then cause the cursor to slip a couple of lines  
down before LyX comes to a halt. The worst slow-down appears when  
the cursor happens to be in a sub-level of a math formula, such as  
a subscript. It can take about one second to get out of a formula  
environment (which is an unacceptably long time when you're in the  
flow of typing).


Another issue is that the scroll bar on the LyX window doesn't seem  
to work properly. Clicking on areas that usually create a page- 
down, I just get a line-by-line scrolling behavior.


Finally, my issues with screen fonts for special math symbols such  
as \iiint are still unresolved (bugzilla bug 2326) in 1.4 binary.

Jens

I run Lyx 1.4 on my G5 dual proc 1.8 Ghz processors w/a gig of ram  
and it's slow as molasses. It's so slow that I literally type faster  
than it can handle, I often have to stop and wait for it to catch up.  
I haven't seen such awful performance since I used to run terminal  
applications over a 1200 baud modem.


I'm trying my best to still use it but I suspect I would be best  
uninstalling and going back to the previous version. That ran just fine.

There are performance problems on Mac. (I've just updated the wiki  
page --  to reflect the  
announcement of 1.4, and this is one of the issues I mention there.)  
For me, what's most annoying with LyX/Mac 1.4.0 is working in insets  
like footnotes: typing and editing is quite slow. Scrolling speed is  
also an issue.


There is a preliminary patch for this issue that is currently  
undergoing testing, and we are trying to make other speed  
improvements as well.

Hi all,

compared to LyX 1.3.6 which I used before, the new version is _quite_ 
slow for me in rendering documents with a fair amount of graphics and 
formulas (talking about a 10page document with maybe 15 200K-eps-files) 
and some formulas.

inbetween.

generating the graphic-previews was changed, with a side effect of 
decreasing responsiveness.

I like the new features in 1.4 (!!!), so I wouldn't be happy to move 
back again...
