Whenever I play on the 1.17.1 or 1.17 versions including 1.17 optifine my frames drop from 20-80 when usually I play at 100-400 frames. Before my lag my render distance was set between 25 to 30 chunks but now I don't notice better performance until 15 chunks or lower. Nothing helps my performance as much as render distance. Either everything is the lowest quality and a good render distance, or best quality and have my render distance from 6 to 2. In the attachments the one with the 1300/300 frames was a peak I had before the lag. the 42 frames is my game at 20 render distance and the full screenshot was with my render distance at 2.
