Both GTK2 ? For the opeing of a project with *m any* files?

But well yes, if you had a 0.9.29, that already had the loading 
optimizations (and was faster than 0.9.28) then that could be.

Obviously the speed isn't constant. New features get added, the may take 
time while loading. The idea can not be, to keep the time always 
constant, or getting faster only. Then many features could never be 
added (your elastic tabs, if ever done, might mean a slow down... / 
though that falls under the deferred-to-idle scans).


In Laz trunk there where some speed improvements for project loading 
again (IIRC)

interesting. Gtk1 does not have support for propper scrolling. So 
scrolling in synedit under GTK1 is considerable slower.
Though the scroll support under gtk2 was only added quite late. So for a 
long time that may have been true.

Otherwhise I can not tell much about gtk2. But then one would need to 
have some fundamental info about the difference of speed of the 2 GTKs 
themself.

You mean between gtk2 and gtk1? Well I can not speak about that.

The "blank" is partly intentional. Older lazarus did add tab by tab, 
updating tabs that wouldn't even be displayed. there was no point in 
that.  That change was made in the IDE, affecting all widgetsets.

Very interesting.  I just added the 450 univint files to a project in 
mseide (though under windows, while all other tests where done under linux)

It takes 15 seconds to open (so yes it is a little faster than lazarus, 
but not such massively)


My version may be a few month old....

All I know is, when I open the ide project (mseide ide project / 
whatever the projectfile is called) itself, and then try to open file, 
it always prompts me for missing form files or similar...

Then again, maybe my config got screed along the way...

as for it codetools equivalent:  Some thinks don't jump, but may be my 
config. I found a link I just clicked, which took over 2 secs before the 
mse-ide actually jumped (at least it showed a "busy" mouse pointer)

Let me just stress out: I do not mean in any way to say, that this is in 
anyway something bad about mse-ide. I only observe that some of the 
statements made before are not reproducible n my system. MSEide does 
require time too (memory I have not analysed.)
