Bug#337573: ITP: preload -- an adaptive readahead daemon

2005-11-12 Thread Petter Reinholdtsen

This ITP is similar to my readahead ITP #325885.  I suspect only one
of these packages is needed in Debian.  Do you recommend preload over
the ubuntu readahead package?

This issue has been discussed a bit on the initscripts-ng mailing
list.  Are you on this list?

I don't know.  But the point is a bit moot now...  preload is already
uploaded to the archive.  It'll take a week or so to arrive to
unstable now.

No.  First time I've heard of that list.

Besides, upstream's documentation mentioned that using preload during
boot actually slowed down the boot.  I've put preload start relatively
late during the boot.

From the NEWS file:
This is the first public release of preload.  It runs as a daemon and
monitors processes through /proc and predicts applications that may
run and prefetches binaries and shared object.  In my experience, it
reduced the startup time of OpenOffice.org writer right after a reboot
from 13 seconds to 7 seconds, and Firefox from 9 to 7.  It also decreased
the time from entering login/password information in gdm to a usable
dekstop is loaded from 37s to 32s.  On the other hand though, the time
from power button is pressed to gdm login screen is functional, was
increased from 65s to 85s, due to excessive harddisk activitiy caused
by preload.

I haven't performed any benchmarks myself.
