Mint 16 boots in less than 5 seconds here*, what exactly would you like to improve? Granted, with old hardware it takes longer, but that can hardly be improved by OS design.xsog wrote:i find the boot time really slow wish it could be speeded up.
takes 5 mins for me and hardware is only 2 years old.recluce wrote:Mint 16 boots in less than 5 seconds here*, what exactly would you like to improve?

*boot time from Grub Menu to Login Screen (Core i7, UEFI boot, SSD)
I agree that the 5 seconds is extreme - this is a powerful high-end desktop with a really fast SSD on a SATA III channel. But it shows what is possible. For comparison: older core i7 laptop with SSD on SATAII channel: about 10 to 15 seconds, Intel NUC (core i3 with mSATA SSD) about 15 seconds, Intel Atom with old notebook hard disk about 90 sec.karlchen wrote:Hello, xsog.
5 seconds as well as 5 min. seem to be really extreme values.
Personally I have never seen a machine that managed to make the way from the Grub boot menu to the MDM greeter logon screen in 5 seconds. But none of the machines here has got an SSD. They all boot from good old SATA II disks.
The average time here will be up to 60 seconds from Grub boot menu to the MDM greeter screen. And anything between 15 sec. and 45 sec. once the logon credentials have been confirmed by pressing the return key till the fully functional desktop will be displayed.
5 min. seem to be an unreasonably long timespan. This suggests that there must be one or more processes which cause substantial delays. It is not too likely that this points to a design flaw, rather to some kind of configuration issue on your system.
The logfile /var/log/syslog where the whole startup steps get logged and which also logs pretty precise timestamps might give hints where long delays occur.
Kind regards,
Karl

A ton depends on packages installed as well... It will be interesting to see how boot is effected once Ubuntu goes to systemDDrHu wrote:You can play around with boot loading

--if it really important to get the fastest boot available on your specific machine..
Other issues are the number and types of service started by the OS..

Okay, sounds like you're running an external IDE HDD via a USB 2 connection into your PC, yes? That's the problem right there. It doesn't matter how old your PC or your HDD is. Compared to an internal HDD hooked into either either an IDE or Sata connection, a USB 2 connection's throughput is dead slow in comparison.xsog wrote:it could be becuase my hdd is ide and running through a usb adapter into my sata pc

Seriously: maybe your hard drive is not in a very good health, taking ages to read data, too.
It is not the answer that I expected What does the command ouputs for these lines:xsog wrote:ok thanks hdd is western digital.eanfrid wrote:2 out of the 3 HDD I bought recently were defective from the start or at least in less than 1 month Check SMART data with:Code: Select all
