Interesting little CPU test

[aaa]

So I found out about Pipe Viewer. Neat little utility that let's you see the progress of some normally silent commands.

A more frivolous thing you can do with it is a CPU test:

Code: Select all

$ pv </dev/zero >/dev/null
81.4GB 0:00:05 [18.1GB/s] [    <=>                                            ]

That's on a T40 with 1.5ghz Dothan.

Post your results, people .

Wow, much less throughput than your T40: 4.47GB/s pv is neat -- thanks.

x61s with 2.6.24 686-smp:

Code: Select all

io@shrimp:~$ pv /dev/zero > /dev/null
 475GB 0:01:46 [4.47GB/s] [           <=>                                                                                   ]
