Can someone tell me why compiling videos is so slow in Blender?

I’m not talking about rendering a scene here, I’m talking about importing a video file to the video editor and maybe trimming it a bit then rendering it out as a video file, Blender seems to be significantly slower at processing the video than most video editors I’ve used in the past and I’m wondering if anyone knows why this is?

I cannot answer your question, but it puzzles me why you use Blender as a video editor…
