5 Well, what strange results. Desktop responsiveness is drastically
6 improved. On the other hand:
7
8 $ time (sudo emerge --sync)
9 [...]
10 real 10m3.185s
11 user 0m6.331s
12 sys 0m0.575s
13
14 This is with a Gentoo rsync server on the same LAN segment. A P4 box on
15 the same segment recorded about 65s for the same command - nearly 10
16 times as fast.
17
18 On this box, calculating dependencies took about another 10 minutes,
19 though I couldn't time it accurately because it's only part of a
20 process. I was watching gkrellm and its display of CPU load while
21 simultaneously running four instances of BOINC clients (one per core) at
22 large niceness levels, and in the graphs I couldn't see any sign that
23 emerge was running at all.
