Rounding up a few loose ends:
The OpenSolaris Visual Panels project has now started. This really interesting stuff, especially from my viewpoint of developing SolView and JKstat. I agree with JC Van Nieuwenhoven's comment - that managing Solaris with a GUI is a pain - and it's good to see efforts underway to fix this.
(One thing I would say, though, is that good GUIs aren't just for novices. While I might know the 16 arcane commands to configure something, would I rather have a good gui and press 1 button? If it was a good gui, yes!)
Following on from my application profiling to see if a T2000 would be a good thing, I found this article that explains a little bit more about what sorts of behaviour might throw off the statistics. Based on this, I think my machine is spending a lot of time in memcpy.
I also notice that the Ultra 45 workstation lists a 146G SAS drive as an option. I can't see this on the published price lists for the X4x00 or the T2000, but I hope it's on its way as it would help address one of the problem areas I've been having for a while.
