[Bug 97456] Re: eBox 2300 boots VERY slow with Ubuntu/LTSP-5
As far as I understand from Oli's comment #20, it's already booting the system as fast as it possibly can with a 2.6 kernel.

On Ubuntu 8.04 w/ LTS 5.0.40, servicing series 2300 eBox's, default- install boot times are still upwards of three full minutes. Comment 17 hints that improvements have been made, but I'm not seeing them - is there something non-default which needs to be enabled and/or installed?

Gavin, it's all been done already and Ollie and Scott have made great progress in getting the boot speed fixed. I think they've got the boot down to about 90 seconds now, which is quite a bit better than it was. They've still got a few tricks up their sleeves, so I expect it to get better yet.

[Bug 97456] Re: eBox 2300 boots VERY slow with Ubuntu/LTSP-5
I used the ubuntu kernel source for 2.6.20, and built a kernel for LTSP-4.2. I modified the .config extensively, turning off an awful lot of stuff that a thin client doesn't need. I probably turned off too much stuff, but it's enough to prove that the 2.6.20 will boot with ltsp-4.2 AND, it boots fast. The interesting thing to look at is around line 96 (13.942148 secs) where the initramfs is unpacked. In the kernel supplied with Ubuntu/LTSP-5, that event doesn't happen until 49 seconds into the boot. You can see that in the syslog that I attached earlier. So, why does my ltsp-4.2 kernel get to that point 36 seconds faster? Is there some settings in the ubuntu kernel config that the SiS CPU doesn't like? Next thing I want to try is building a kernel for Ubuntu/LTSP-5 using my .config file, to see how well it performs. And certainly, more comparison between the 2 syslog files is required. ** Attachment added: syslog output from ubuntus 2.6.20 kernel built for LTSP-4.2 http://librarian.launchpad.net/7039443/syslog.ws028 -- eBox 2300 boots VERY slow with Ubuntu/LTSP-5 https://launchpad.net/bugs/97456 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
