Don't know how much known this is: Apple provides a wonderful easy to  
use profiling application for OSX, called Shark. You get it here for  
free (maybe you have to register for the ADC website, but it's free):


  http://developer.apple.com/tools/download/

Shark is part of the package Computer Hardware Understanding  
Development (CHUD) Tools

version 4.4.4 (DMG). You can see how it looks like here:

 http://developer.apple.com/tools/sharkoptimize.html

If you have performance problems, that's the tool to use to find out  
where the cpu cycles are spent. I guess you need a LyX binary with  
symbols inside, so unstripped.

Just for the info.

I've tried your new universal-test and the ppc version posted by  
Gerard. I'm

using a 600MHz, 384MB ram, OS X 10.4.9 ppc machine.

Both versions are essentially unusably slow when typing in figure  
floats. I
don't know what version of Qt Gerard used for compilation (probably  
not
Qt4.3 since math preview display is normal size and the Times font  
works

correctly). However, his version is faster at loading the program and
standard typing in a new document is almost normal whereas in your  
universal
version typing in a new document without any figures or math is  
still slow
and the program icon bounces several times while loading whereas  
Gerards

version bounces two or three times then loads.

I've now dual-booted my Mac with Linux and I'll be using LyX in  
Linux since
this slowness is less pronounced (although still noticeable). I've  
found
Debian to be the most responsive when using LyX so far in my distro  
testing.


I'm not sure if upgrading to 640MB would make a significant  
difference or
not since it's still a 600MHz processor, if anyone thought it would  
make a
truly significant difference I would upgrade. I'll probably just  
plan on

upgrading laptops soon. It's time for an x86 Linux laptop :-}.

Thanks for all the work,

This new test-version runs without typing lags on my G4 1.25Ghz,

I have tested this on a new document as the typing lag I experienced  
with the first rc-Release happened independently of the document  
length and always.

is shorter.
Would it be so bad to have two separated Versions for PPC and Intel

This note is for PPC Mac users only. (Intel Macs are not affected  
by this.)


LyX-1.5.0 RC 1 for Mac was originally released as a universal  
binary, and that release was quite slow for PPC Macs. I have just  
posted a new version that should improve speed on PPC Macs, and I'd  
like for people experiencing speed issues with the original release  
to try this one instead. It can be found here:


http://edisk.fandm.edu/bennett.helm/LyX/LyX-universal-test.app.zip

If you're willing to test, please report on the following:

1. Do you experience a lag between what you type and when it  
appears on screen with this new version? Please try this in normal  
text as well as in insets, like footnotes, and math and note  
environments.


2. If you do experience a typing lag, please provide some detail as  
to the circumstances you find it:

  * How big is your document?
  * Does it have equations? (Lots?)
  * Does it have figures? (Lots?)
  * When do you notice it most?

3. Provide some details about your computer: processor type (G3,  
G4, G5) and speed, Mac OS version, amount of RAM.


If any of you are compiling your own versions of LyX, please  
compare the new version I've just posted against the version you  
compiled. Is one noticeably faster than the other? (Try timing how  
long it takes to page down through the User's Guide, e.g. -- but do  
it twice, reporting the times from the second run for each version  
of LyX.) Also, please provide details of how you compiled LyX,

Oh, you're right: There is only a difference at first time starting:
While the PPC version needs approx. 6sec the Universal binary takes  
almost 20sec for a first time start.

All later starts of Lyx take equal time (6sec).

Just for the info.

I've tried your new universal-test and the ppc version posted by Gerard. I'm
using a 600MHz, 384MB ram, OS X 10.4.9 ppc machine.

Both versions are essentially unusably slow when typing in figure floats. I
don't know what version of Qt Gerard used for compilation (probably not
Qt4.3 since math preview display is normal size and the Times font works
correctly). However, his version is faster at loading the program and
standard typing in a new document is almost normal whereas in your universal
version typing in a new document without any figures or math is still slow
and the program icon bounces several times while loading whereas Gerards
version bounces two or three times then loads.

I've now dual-booted my Mac with Linux and I'll be using LyX in Linux since
this slowness is less pronounced (although still noticeable). I've found
Debian to be the most responsive when using LyX so far in my distro testing.

I'm not sure if upgrading to 640MB would make a significant difference or
not since it's still a 600MHz processor, if anyone thought it would make a
truly significant difference I would upgrade. I'll probably just plan on

  * configure flags
  * Qt version

Thanks.

LyX-1.5.0 RC 1 for Mac was originally released as a universal  
binary, and that release was quite slow for PPC Macs. I have just  
posted a new version that should improve speed on PPC Macs, and I'd  
like for people experiencing speed issues with the original release  
to try this one instead. It can be found here:

Though I have to say that the startup time for the PPC-only Version  
is shorter.


Does that happen only the first time you open LyX or all the time?
(If you open LyX by double-clicking a document read the first time  
you open the document)
The reason I ask is that there is some caching going on so there can  
be a big difference.

Oh, you're right: There is only a difference at first time starting:
While the PPC version needs approx. 6sec the Universal binary takes  
almost 20sec for a first time start.

All later starts of Lyx take equal time (6sec).

This new PPC version works allright. it may be a little quicker than  
the universal one, in particular for math previews, but I do not feel  
a major change. However, I had not experienced a typing lag  with the  
universal version. One advantage of the PPC only version is that it  
is slightly smaller.

Just for the info.

I've tried your new universal-test and the ppc version posted by Gerard. I'm
using a 600MHz, 384MB ram, OS X 10.4.9 ppc machine.

Both versions are essentially unusably slow when typing in figure floats. I
don't know what version of Qt Gerard used for compilation (probably not
Qt4.3 since math preview display is normal size and the Times font works
correctly). However, his version is faster at loading the program and
standard typing in a new document is almost normal whereas in your universal
version typing in a new document without any figures or math is still slow
and the program icon bounces several times while loading whereas Gerards
version bounces two or three times then loads.

I've now dual-booted my Mac with Linux and I'll be using LyX in Linux since
this slowness is less pronounced (although still noticeable). I've found
Debian to be the most responsive when using LyX so far in my distro testing.

I'm not sure if upgrading to 640MB would make a significant difference or
not since it's still a 600MHz processor, if anyone thought it would make a
truly significant difference I would upgrade. I'll probably just plan on
upgrading laptops soon. It's time for an x86 Linux laptop :-}.

Thanks for all the work,
Bob Lounsbury

Don't worry -- I'm stripping all that out to make it as fast as  
possible (and those configure settings are specified in the  
INSTALL.MacOSX file). The trouble is that when cross-compiling with  
the same configure settings, the PPC version is much slower.
