Stupid T-61 vs Dell Optiplex 330 Gutsy Shootout

So I was wondering graphics performance on my son's new workstation is so much worse than on my Thinkpad. In particular bzflag, because I thought they both had the same Intel graphics card, when I bought it. And I was sure it wasn't the CPU? Well it turned out I was wrong and my little benchmark to unzip the Thoughtpolice FreeBSD 6.2 VM had some suprising results. Yeah I know I should get some real benchmarking software but I didn't feel like it.

Intel(R) Pentium(R) Dual CPU E2140 @ 1.60GHz (1GB)
82G33/G31 Express Integrated Graphics Controller
real 0m22.276s
user 0m10.480s
sys 0m1.540s

Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz (1.5 GB)
Mobile GM965/GL960 Integrated Graphics Controller

real 0m45.863s

Just as I suspected (after finding how fast is your disk it is the IO that is killing my Thinkpad.

root@nikplex330:~/vms# hdparm -t /dev/sda

Timing buffered disk reads: 278 MB in 3.02 seconds = 92.13 MB/sec

root@gutsy61:~/torrents# hdparm -t /dev/sda

Timing buffered disk reads: 120 MB in 3.04 seconds = 39.44 MB/sec

Of course I'm also using reiserfs on my laptop (out of habit and b/c I've never had any issues) but doubt there should be double.

No wonder my VM's lag so bad some times.
