[RESOLVED] software runs late after compilation

[Mojtaba]

Hello friends, I have a strange problem, I use LabelPlus control
When I run the software in vb6, it runs fast, but when I get the output and run it, it takes a long time to run.
Interestingly, when I test the same program in the same system and other windows, it runs quickly!
This problem is specific to this LabelPlus control, and other programs compile and run quickly
Watch the movie . . .

Turn off your AntiVirus (or better add your working directory where you regularly compile test projects to its exception list) and test again.

I bet he uses Avast...

The first thing I thought of was the antivirus, but the problem is not the antivirus
I completely disabled the antivirus and even deleted it.
Cleaner Windows with Windows Optimer and Cleer software
I updated the dlls like gdiplus.dll|
The problem was not solved

No, it is not Avast
I use Advanced SystemCare Ultimate software

I found the problem : Due to the installation of many fonts
I realized that all programs using GDI+ need to cache system fonts every time they run.
And this causes the software to run late

Solution:

1 - Many fonts should be deleted, but this is not a wise action on the customers' systems.
2 - The project should be limited to only the fonts that are needed, not all system fonts.
If there is a better solution, please share

I deleted many fonts
See the result of loading the program in the video

Deletion of fonts was once a factor on older machines that were significantly slower. Faster machines these seem to have negated that problem.

How many fonts did the system have? I have a GDI+app but the system has a mere 109 fonts installed.

If you add/load the fonts back in again, does the GDI+ app start to slow down again? you might need to do this to prove your theory.

2 - The project should be limited to only the fonts that are needed, not all system fonts.

When is this not always the case? Why would anyone load *all* system fonts in their app?

Might be a combobox for font selection which features a font preview like in WinWord:

He seems to imply that just having a lot of fonts on the system slows down any GDI+ app, then he briefly states that a GDI+ project should not load all system fonts... Why would you load all system fonts?

I don't know what is going on here.

In my opinion, there is no difference between the old and the new system. I tested it on multiple Windows and 2 advanced systems
All software that uses GDI+ caches all Windows fonts in one file.
The larger the number of fonts, the longer the caching time and, as a result, the longer the program's execution time
I design and I need a lot of fonts, I have almost 1500 fonts
To prove your theory, if you watch the previous two videos, you will understand
If you want to understand it more, I will make a new video and tell you where the GDI+ save files are stored at runtime and more information.

Yes, this is exactly the main problem
Fonts should not be cached every time when running GDI+ software

Because you are following this discussion
Let's do a hands-on project together to understand the topic better
I have included a sample gdi+ project, first compile and run it without installing fonts
I also put a collection of fonts, new and useful 600 fonts 20 MB
Install the fonts
Now run the software again
Note: Run the software outside of VB6

Font package

Does your application need all those fonts or do you just have them for some other reason?

The thing is that I don't use any of the fonts installed in Windows in the project and I don't need them.
But the program loads slowly due to the installation of many fonts
Problem gdi+ caches system fonts every time the program is run

[yereverluvinuncleber]

FYI - my old system, i7 6700 with 109 fonts loaded runs your GDI+ test program instantly. I don't have a test system with hundreds/thousands of fonts loaded so I cannot test further. If there is anyone else out there who has a test system where they would be happy to load fonts in quantity then please feel free to provide your results.
