"This not only eliminates the collision handling that the kernel handles internally, but also creates even more collisions for telldir(). Discounted."
Are collisions an integrity issue or speed issue?
We have always used EXT3 becuase reiser always seemed to corrupt so easy and we didn't use NSS becuase by the time you add the dependencies like edirectory we saw the memory overhead as counter intuitive.
I would love to see some benchmarks!
