Sheeva Plug Server Migration?

So, I’m back onto looking at an alternative to my old P3 based server.

I wanted to know the hardware specs of the Sheeva CPU though as even though its 1.2GHz I don’t think its going to be as fast, so I thought I’d check.

I found a page online:
(http://computingplugs.com/index.php/SheevaPlug_Performance)

I had some problems compiling nbench on my desktop, so I had a look around and found one result which helped, it was in Danish, but essentially I had to change this line in the Makefile:

# generic options for gcc
CFLAGS = -s -static -Wall -O3

to this:

# generic options for gcc
CFLAGS = -s -Wall -O3

then ran make and it was fine.

Here are the results from nbench on my server:

I’m now not so sure if it’s worth upgrading. I’ll have to look into other factors. On the site above which benchmarked the SheevaPlug they state:

“From nbench’s website, the Sheeva Plug falls somewhere around a P3 800Mhz range.”

which is exactly what I’m running in my current Compaq DeskPro Server.
