I fell into that trap as well, and was doing performance testing on kernel 2.6 before I realized that things were in debug mode. Test3 is a more appropriate platform, as it's more of an RC1 than a test release. > >2) Fedora Core 2 Anaconda DOES support xfs/jfs/reiserfs.

I seem to remember them in the release notes, but I could be wrong. It might be one of those "undocumented" features. > >3) Fedora Core systems are build around ext3.

If your goal is to compare file systems, then you should use the appropriate OS. If your goal is to compare Fedora Core 2 with different file system options, then yes, use FC2. But don't confuse FC2 results with general file system results. > >4) NFS may not be an optimal test.

Limiting the outside factors is necessary in order to generate the baseline, against which all other tests will be compared against.
