Tuning the systemd boot

shawnjgoff · 2012-10-15 01:16:27

You can see a good boot on Poettering's blog: http://0pointer.de/public/blame2.svg
And here is my boot: http://imgh.us/bootplot.svg

Notice mine has lots of strange lateral pauses and I don't see anything causing them.

Any ideas for what I can do to figure out what is causing these long pauses?

Moving to Applications and DEs...

No I don't notice because the link to your boot is borked.

The link worked fine for me.

It looks like the same type of thing that happens in mine: boot plot

Interesting, when I click (or follow, since I use dwb) the link, it gives me a 503. But when I type out the path it totally works. Interesting....

Anyway, it seems as though the stall is only a second and a half. I've seen this a few times before, and I have not come across a solution (or a cause for that matter).

I get the 503 with Javascript off but works otherwise.

I just noticed the same too on my laptop yesterday. I was going to look into it today. I will share my findings

There is over a two-second delay before the tyySn devices come up as well as over 1.5 seconds before eth0 comes up. I can't tell what either of those things are waiting on. The sda 7, 2, and 3 also seem to be waiting for something, although those are less extreme.

I wonder mostly what's with the gray kernel and userspace bars. Why don't "normal" bootcharts like Poettering's have this?

I suspect it's because he ran it inside a container. It doesn't say this, but I know that is a feature that he had been working on for a while.

I believe the long pause in userspace before mount is the initramfs, since its job is to mount the root filesystem.

I think it might also have something to do with e4rat, which I use. That does take a while to load its settings, but from there on it's blazingly fast - especially into X.
