8 I too was wondering why a Toshiba HDD 1.8" MK2431GAH (4kB-sector), 240
9 GB I've recently obtained was slow:
10
11 -> time tar xfj portage-latest.tar.bz2
12
13 real 16m5.500s
14 user 0m28.535s
15 sys 0m19.785s
16
17 Following your post I recreated a single partition (reiserfs 3.6)
18 starting at the 64th sector:
19
20 Disk /dev/sdb: 240.1 GB, 240057409536 bytes
21 255 heads, 63 sectors/track, 29185 cylinders, total 468862128 sectors
22 Units = sectors of 1 * 512 = 512 bytes
23 Disk identifier: 0xe7bf4b8e
24
25 Device Boot Start End Blocks Id System
26 /dev/sdb1 64 468862127 234431032 83 Linux
27
28 and the time was improved
29
30 -> time tar xfj portage-latest.tar.bz2
31
32 real 2m15.600s
33 user 0m28.156s
34 sys 0m18.933s
