Re: Linux filesystems & oracle performance

I'm assuming that Nuno was talking about the Linux Maximus paper.

Nuno,

That is good information to note as we are preparing down the road to Oracle on Linux. I bet you are right that the paper just used the default block sizes. It would be very easy for the author to set both file systems to use the same block size and repeat the benchmarks.

HTH,
Brian
