Time to build GenBank on a SunFire server

Thanks Steve,

That was my gut feeling, but not having experience with GCG on a Sun, I
wasn't really sure what to expect.

Normally (even in the past on our old SGI) I do GenBank full release builds
manually (albeit building portions simultaneously), and just script
maintenance releases.  SRS indexing is always the last thing I do - it has
never crashed on me, but is slow.

We just seem to be getting terrible IO lag with this machine, and I think we
need to get someone from Sun down here to take a look at it.  Admittedly, we
did buy just about the worst SCSI card Sun sells for the SunFire series, but
even that seems like it couldn't account for the IO performance we are
seeing.

Thanks for your comments.

Michael
