So, I've built Kei, the Pentium 4 2.6GHz super wizzy box, and installed Fedora on it as well. How does it run? Let's find out!

Test 1: Woot*625

Yuri	1.26
Kei	1.46
Kei x2	2.93
Misa	2.83
Kodachi	2.49
Lina	4.09

Yuri's rating of 2800+ looks realistic as it pips Kei's P4 2.6 by about 15%. On the other hand, the Pentium 4 2.6GHz is nearly twice as fast as the Pentium 4 Celeron 1.7GHz.

Kei x2 shows the average CPU time for two copies of the same code run simultaneously with HyperThreading enabled. Here we see no advantage from HyperThreading at all: At 2.93 seconds the programs take just as long to run in parallel as they would in series.

Test 2: Memory Exerciser

	User	System	Total
Yuri	3.29	1.12	4.41
Kei	0.88	2.30	3.18
Kei x2	1.71	3.55	5.26
Misa	2.12	5.05	7.17
Kodachi	8.25	3.27	11.52
LIna	7.11	6.88	13.99

But now Kei steals the lead - and by a healthy margin. As I had expected, the 800MHz front-side bus really delivers the goods when you're tossing 48MB strings about.

Also, we see a marked improvement with two copies running simultaneously: The total time for two runs drops from 6.36 to 5.26 seconds - about 20% faster.

Test 3: Cache Cruncher

Yuri	3.77
Kei	7.29
Kei x2	9.96
Misa	10.87
Kodachi	6.20
Lina	9.50

Ouchie! Kei falls in a heap, outperformed by a 1.2GHz Athlon. A sad day for Intel, a sad day for - me, because I bought the darn thing. In proportion to clock speed, Kei delivers the same performance here as Misa. Kei claws back a bit of respect, though, with a hefty 46% speed gain from HyperThreading.

So, the conclusion we draw from this is: Um.
