Re: [lazarus] Lazarus 0.9.18 and compilation speed (what does it look for?)

[Alex Smirnov]

Vincent Snijders Thus I think that all this 111 seconds is almost wasting time that was spent in FindFirst/FindNext circle. I think that is wrong. But you can test that by copying all the needed .ppu and .o files into one directory and replace the -Fu lines for fpc.cfg with -Fudirectory_with_all_needed_units. I think most time is spent creating the executable from the 383 units it needs, getting code, data and debug sections from the 383 units and putting it in the final executable. Vincent Yes, You are right. When I set Compiler Options -> Messages to "Show summary" only it takes 15 seconds to make all project and also to link it. Ok. But 15 seconds is also very large time. Sorry for that - I mean Delphi. It is faster in all cases. So I think it is a good idea to speedup compilation process. May be for Windows only - if you will set the file search process to be case insensitive it will  decrease the quantity of requests in 4 times! Also - it seems that the component for Lazarus Massages window (TMemo?) is not working good. It seems that every time you add a line there it starts to draw itself from the first line - as a result the system spends a lot of time in TMemo redrawing. :-) I will try to check this.
