Both these machines used the same hard drive, external box. USB2.
Both with 2.6.39 linux kernel, also the userland was configured with the same profile.
They used the same version of gcc, binutils, and glibc.

So, mr.LittleCube/Hz is 2X mr.OrangeBox/Hz :D

Masochist.

I'd rather use a PIII to a Netburst machine any day simply because the latter at least consumes power in accordance with it's performance.

I happen to have one here (a ProLiant DL380 G2 w/2x 1.4 GHz Pentium III-S) and I had to install Windows XP on it to be able to run a firmware upgrade via SCSI for an older Tandberg StorageLoader. It was the only "true" i386 machine with room for a SCSI controller available to me then (and still now).

Impressive result! I didn't knew those PPC74xx have that much juice in them.
Sorry, no comparable results available. But I could do a openssl speed -elapsed on OpenBSD 6.1 tomorrow as a start.

Regarding Netburst, there were a few later systems with Netburst CPUs (Xeon 7000 and 7100 series) that had cool features, like memory mirroring and/or memory hot-plug. I think of the ProLiant DL580 G3 and G4, later systems (like the G5) no longer supported memory hot-plug. Sadly the mechanics of those hot-plug memory modules (each of them takes four DDR2 DIMMs) are bugged: it's sometimes terribly hard to unlock them and how cool is hot-plug if you can't get the module in question out of the machine? :roll:

I personally think when it comes down to it that Nehalem and up are still quite usable but below that is at best questionable in it's usability for x86, I do have a P4 era box but it has a Pentium M, so it at least consumes a reasonable amount of power.

Also bought a cluster of mac-mini! Two are PPC-G4, two are x86-i2. They are stacked together as tower, with glue layer between them. A lan switch on the top, with five ports 10/100/1000 auto sensing, and they all join the lan through NFS.

PPC-nodes are useful and faster when you want to test 'stages' without the need of passing through qemu-ppc.

Unfortunately there is no mac-mini/MIPS :lol:

A Netburst just sucks power and will sit there crunching it for longer than necessary. A G4S at 1.5GHz ran circles around my P4 3GHz especially in the media metrics (altivec probably)


To be fair, it's a 3.4GHz Presler Pentium D so it's just about the best NetBurst CPU you can possibly find. And with 4GB of RAM it's surprisingly quick!

(Re)built current Debian 8 and Debian 9 Linux kernels for MIPS based Cobalt machines using my xw9400, two changed root environments and QEMU user mode emulation. Both work well with my first Qube 2 (not tested with RaQs yet, but I assume they will also work there).
