Is this the correct bug report for this issue? On my quite new laptop
(dualcore 2.2 GHz AMD CPU, 3 GiB of RAM, a 320 GB HDD), sreadahead
consistently slows startup down by about 5.5 seconds.
I measured this with the following job:
start on login-session-start
task
script
cat /proc/uptime >>/uptimes
if [ "$(wc -l /uptimes | cut -d' ' -f1)" -lt 5 ]; then
reboot
fi
end script
The average measured time with sreadahead disabled is 33.07 s, and with
sreadahead enabled, 38.55 s.
Could something as simple as making the rest of the startup wait for
sreadahead to finish fix this? The problem might simply be caused by
thrashing when sreadahead is doing its thing simultaneously with the
rest of the system booting.
