The RE_render_result_rect_from_ibuf function (used only by VSE) was allocating memory for the render result, clearing it to zero and immediately overwriting it with the image pixel data. Remove the "clear to zero" part. Rendering a 1920x1080 resolution movie with VSE (using float pixel data), average RE_render_result_rect_from_ibuf time goes from 6.8ms down to 3.8ms Pull Request: https://projects.blender.org/blender/blender/pulls/135170
