After many years with an old desktop machine (AMD K7 900Mhz engineering sample), I had to admit that my workstation needed an upgrade.
Similarly, my old trusty T42p laptop has not liked travelling too much and the last time I got it fixed at work, I was told it was the last time :)
Since I had just upgraded my ancient original Pentium2 Dual Xeon 450Mhz server (gargamel) last year to a more acceptable Dual P4 Xeon 2.4GHz Hyperthreading, it was time to do my workstation and laptop this time.
For the workstation, I pieced up and built a brand new up to date machine: Dual Core Duo E6850 3GHz with Asus board, and giant tower with 11U, and 12-14 drives.
For the laptop, I got a Thinkpad Z61p: Dual Core Duo T7200 2Ghz with 1920x1200 resolution. The LCD is unfortunately a bit smaller than my T42p, but the pixels are still quite readable for me.
As for the OS, I'm currently switching from an almost 10 year old hand configured/upgraded debian distribution (with a fair amount of upgrade cruft and bugglets) to Ubuntu Fiesty. I'm currently forcing myself to use the default gnome, at least long enough to see what I've been missing, if anything, and whether I can put up with it (the lack of edge scrolling, and pitiful iconbox compared to enlightenment is already annoying me). But eh, it's a learning experience and lets me start from a clean system. Once every 10 years isn't too bad compared to windows (which I had to re-install after being unable to migrate it from my older desktop)
For comparison purposes, here are performance comparison numbers between my old and new new server, laptop, and workstation (doing a kernel build with multiple levels of parallelization (-j))
The new server is almost 20 times faster than my 10 year old server:
The new laptop is 2.5 times faster than the old one, although it'll be a lot more responsive than the old one with the second CPU core:
That said, the winner is my new workstation, top of the line of current CPU and memory speed (800Mhz DDR2, ok, DDR3 was 3 times the price, which is a bit much). What's nice is that it actually beats gargamel, my 2.4Ghz dual CPU server by a factor of 3. Impressive!
Of course, the best part is that least 15 times faster than my old workstation. I guess the old was, was old :)
The rest is a benchmark of two SATA boards (Silicon Image 3124 vs 3132) through a port multiplier on the faster workstation (moremagic) vs the server (gargamel). Reading speed is 150MB/s and writing speed 120MB/s in raid5 configuration in the fastest setup. Not to shabby :) (it would likely be faster without the port multipliers, but eh, who has 14 sata ports in his workstation? :) )
