Long as the program runs on another computer:(((

[abmservice]

I wrote a program using Lazarus. Program on the computer where Lazarus runs very quickly. How do I move to another computer that run lasts from 15-20 seconds. Why?
Compiled in Vista. Run in XP. Checked by compiling in XP, is the same: (

I am not sure I understand your question.
You wrote a program on Vista and compiled it there. On Vista it works fine, but on XP its slower???
Am I understanding correctly???
Tell me, do both machine have the same amount of RAM memory?
Do both machine have the same (or equivalent speed)? Processor speed?

Lazarus 0.9.29 -VISTA 32 -4GB RAM -CORE2DUO 2x2GB-Program -OK
Lazarus 0.9.29 XP 32 -512MB RAM -Pentium 1,4 GB - Program -OK
XP 32 2GB RAM -CORE2DUO - Program - Long run -20 seconds:((((

What does your program do ? graphics ? file I/O ? etc.

Database -firebird 2.1 Program to use the bakery and confectionery

What part of the program runs slowly?

Do you mean query execution time or maybe connecting to the database?

I would suggest you to create a simple, very very simple test program so you could easier check where is the problem.

Are you certain that the "slower" machine does not have too many active processes in memory at the time when you are running your program? For example, real-time virus scans, disk defragmenting etc.

I also use Lazarus applications with backend Firebird databases on Windows 2000 Professional, XP & Vista & I've never noticed the problem you are talking about.

put some time measurement into your code. Best is to compile your app with a console (open menu "project"/"compiler options" => go to the linker tab, and uncheck "Win 32 GUI application" (-WG)" / newer lazarus has this under "project options" )

Then you can writeln before and after you call the database, or before and after you do other things => and you can observe where your code slows down.

Also are all 3 computer use the exact same database? (same amount of entries; same indexes? a missing index can easily account for great time losses) Are the databases all on the same PC as the program (local) or are they connected over network?

I tested locally and the database server on linux. I suspect that the fault may be Windows XP. Today I installed xp on a new computer and working properly, the same programs installed on your computer as the problem and working properly despite the fact that the processor is AMD Duron 1.2 GHz RAM 256MB.
Thank you for suggestions. I did not installed any library that is installed by default with Lazarus.
