This benchmark configuration (--iodepth=1 --numjobs=1) cannot benefit from virtiofsd multithreading. Have you measured a regression when this patch series is applied? If your benchmark is unrelated to this patch series, let's discuss it in a separate email thread. fuse_buf_copy() can be optimized to use pwritev(). Thanks, Stefan
