bde 96/12/25 12:15:13 Modified: sys/msdosfs msdosfs_vnops.c Log: Don't synchronously update the directory entry at the end of every successful write. Only do it for the IO_SYNC case (like ufs). On one of my systems, this speeds up `iozone 24 512' from 32K/sec (1/128 as fast as ufs) to 2.8MB/sec (7/10 as fast as ufs). Obtained from: partly from NetBSD Revision Changes Path 1.35 +2 -2 src/sys/msdosfs/msdosfs_vnops.c
