Re: LyX-1.5.0 Release Candidate 1 on Mac PPC: Speed issues (solution?)

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):

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

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

This new PPC version works allright. it may be a little quicker than

a major change. However, I had not experienced a typing lag  with the

is slightly smaller.

Just for the info.

version bounces two or three times then loads.




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

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