[gentoo-server] For a 1.5TB server running Samba and NFS ONLY, what's the best kernel?

[David Wuertele]

I'm rebuilding my terabyte file server from scratch.  Previously I
used "emerge gs-sources" to get my kernel, but I'm considering using
the performance-tuned "emerge gentoo-sources" this time.

I want maximum performance and reliability in these areas:

  on-board Via IDE controller
  multiple SIIG ATA-133 PCI IDE controllers
  7-drive RAID5 array
  1.5TB Reiserfs partition
  Average file size about 50MB, largest files will commonly exceed 2GB
  Samba file sharing
  NFS file sharing

All other areas are of little or no consequence.
Any recommendations?

Thanks,
Dave
