how to reduce ffmpeg compression time

Hi I am new with FFmpeg and I am trying to compress the video file by using this command


"-y", "-i", source_file_path, "-s", "480x640", "-r", "24", "-c:v", "libx264", "-pix_fmt", "yuv420p", "-preset", "ultrafast", "-b:v", "512k", "-bufsize",
"3968k", "-crf", "26", "-c:a", "copy", destination_file_path

currently, it's taking 3 minutes to compress a 1-minute long file how I can reduce the compressing process time. I am using FFmpeg 4.0. thanks
