My steps are:

I am making a model its rig animated 1000-1200 frame in blender and I will export these .obj files, therefore, I have to load 1000-1200 .obj files.
I am using objloader in c++ and I am sending gpu with opengl VBO way
I didn't use multithreading with objloader
All files install in 80 seconds (one file has 2000 face all triangle)

How can I accelerate it?

Do I have to use multithreading? Is it the only way? Then I can't use std::string and std::vector am right?
Can I take only rig positions from blender and can I use them over only one .obj file in OpenGL with gltranslate and glrotate to move? against load all animation model?
Any suggestion?

Don't use .obj. – tkausl Feb 21 '18 at 23:38
what can i use suggestion ? i am beginner – Emre Kaya Feb 21 '18 at 23:40
FBX for example. – tkausl Feb 21 '18 at 23:41
use any binary form 3D mesh representation. The ASCII exports are always slow. I would try binary STL. – Spektre Feb 22 '18 at 07:53

The term you are looking for is *skinning*. With this approach, you store the model and the animation separately. Skinning is the process of applying a (skeletal) animation to a 3D model. – Nico Schertler Feb 22 '18 at 08:00
i heard new "skeletal animation" thank you i wanted to learn this now i need to fix how can use skeletal animation :D – Emre Kaya Feb 22 '18 at 19:13
