What kind of processor/system is that?

I also see quite a difference in untarring gz vs. bz2.

On a Pentium classic with genuine f00f bug, 180 Mhz, 80 MB of RAM,
running Linux 2.5.64, I get:

[rddunlap@eeyore linsrc]$ time tar xzf linux-2.5.65.tar.gz

[rddunlap@eeyore linsrc]$ mv linux-2.5.65 linux-2565

[rddunlap@eeyore linsrc]$ time tar xjf linux-2.5.65.tar.bz2
