Loading the covtype file takes anywhere from 5 to 10 minutes
on a P4 2.8G depending on CPU usage. However, the fact that
covtype matrix needs 1 GB of RAM may be a potential
problem.
※ 引述《ChihJen ( )》之铭言：
: I think you can check how much time it costs on a subset of coveypt..
: For example, try the first 10000, 50000, 100000 and see how the time
: scales.
: This will tell us if 580k is possible.
: If the scaling is linear, 80x40 <= 1hr is good enough.

: : It turns out the code for loading covtype data seems take about
: : 6 minutes on 1.2G AMD CPU XD , while a perl program takes only
: : about 2 minutes.
