Hi, i’ve written a program that draw musicale partitions. The drawing stuffs are done in Frame Buffers with the AGG libraries. The GUIs are created with JUCE.
On Windows the program is very very fast but on Mac/Linux it’s slow. The code is the same from one platform to another, I don’t think the problem could come from AGG because it only uses pure C++ and doesn’t use OS specific functions.
So I wonder if other users experienced this problems ? Is juce known to be slower on Mac/Linux ? The program does the blitting of an image buffer very frequently, perhaps the problem comes from the different OS blitting functions ?
I’ve also tried to change the niceness of the program on Linux but it’s not really quicker.
So, how can I optimze speed on Linux/Mac ?
Ps: Sorry if it’s difficult to understand me, i’m french
