That would stomp all over my claim that nobody has hacked on UFS since I did (which would be fine with me, I liked UFS, be cool if someone moved it forward). (pause while I google) Yep, someone did. I'd like to know who. I found this: http://www.oracle.com/technetwork/systems/linux/fs-performance-149840.pdf Can anyone confirm those results? That would be the first I've heard of Solaris being faster than Linux. If that's true has Linux tried to implement the same sort of logging? --lm P.S. I realize this isn't ancient Unix so I could move this to the linux-kernel mailing list. Though maybe it is appropriate, it's tech from the 1990's - is that ancient enough?
