文件系统的性能测试

For 2.4 kernel
CONCLUSION

For those of you still reading, congrats! The conclusion is obvious by the "Total Time For All Benchmarks Test." The best journaling file system to choose based upon these results would be: JFS, ReiserFS or XFS depending on your needs and what types of files you are dealing with. I was quite surprised how slow ext3 was overall, as many distributions use this file system as their default file system. Overall, one should choose the best file system based upon the properties of the files they are dealing with for the best performance possible!

For 2.6 kernel
Conclusion

With the second round of filesystem benchmarks, I hope everyone is now satisfied with the benchmarks using the 2.6 kernel. What I gleam from these benchmarks is both EXT2 and EXT3 are now roughly the same speeds in the majority of the tests. It also appears the XFS has improved in the majority of the tests. ReiserFSv3 has slowed in many of the tests with ReiserFSv4 being the slowest in most of the tests. It is important to note that JFS has improved in some of the tests. Personally, I still choose XFS for filesystem performance and scalability.
