did yours improve after the mountain lion update?

i noticed mine has slowed down by 30 secs or so. starting my macbook pro (2011) takes about a minute now instead of 20-30 secs.

is this normal? sorry if this was asked before.

Mine is about 16 Seconds which is the same as it was with lion.

Try to doing a clean install

Mid 2009 mbp doing about a minute boot up and ~30sec shut down. Been like this since Lion, with clean install and all.
 
Imac: 26 seconds to useable state, although I rarely shut it down anyway.


MBA: Under 10 seconds to useable state, but SSD is why.

MBP: The slowest of all @ 32 seconds to useable state.

Overall, I can't say I've noticed any marked difference between Lion and ML. I can report that SL was faster than both though.
 
I've noticed a speed in my boot up time, but a lag in my shutdown time w/ ML.

My boot time has decreased to 10-11 seconds from ~14 in lion. My shut down time, however, as increased. Everytime I shut down theres a white screen with a spinning black circle at the bottom. Doesn't really bother me, but it was never present in Lion.
 
Try using verbose boot (⌘v on startup) — this shows which commands are taking time, I find it especially useful on shutdown to see which processes are causing shutdown to hang (usually Parallels!).

One annoying bug in Mountain Lion is that the shutdown_log in Console is now not being updated any more, unlike Lion where it was introduced.
 
Do these commands and then make sure your OSX drive is selected as the "startup" drive in preferences:

Rebuild kernel extension caches
Though you can use a number of maintenance utilities to clear and rebuild the kernel extensions caches, another approach is to run these commands manually in the Terminal. Doing so ensures you know exactly what commands are being run, and also allows you to customize them if needed.

First ensure the system root is owned by "root" and that the group is set to "admin" by running the following command in the Terminal:

sudo chown root:admin /

After this is done, update the prelinked kernel for the system, which will ensure that all previously used kernel extensions are quickly loaded at boot. This will grab any new kernel extensions used for added system hardware and include them when prelinking the kernel.

sudo kextcache -system-prelinked-kernel

After this command is done, rebuild the cache for the kernel extensions by running the following command:

sudo kextcache -system-caches

Maybe spotlight is re-indexing the drive? Just a thought...

how would i know if its doing that? solution?
 
Lion
Boot: 10 seconds
Shutdown: 2 seconds

Mountain Lion
Boot: 7-8 seconds seconds
Shutdown: 2 seconds

Not a profound difference.

If you click on Spotlight at the top right of your screen, it will tell you if it's indexing anything. The solution is to either turn off indexing or let it finish.
 
Upgrading from 10.6 to 10.8 slowed down boot times dramatically. I tried again with a clean install and the boot times sped right back up to where they were before.

You "forgot" to say that you have SSD :D
 
My Mac Mini Server, even with an SSD feels slow to boot up. I'm hoping that Mountain Lion (just bought) will help this!

My target boot drive is setup correctly etc.

I didn't do a clean install but my speeds also dropped dramatically.
 
httpd and mysqld were the culprits in my case

Hi! I was facing the same slow shutdown issue. Tried NVRAM reset, SMC, daemon timeout change etc, didnt work.

Used verbose mode and saw that httpd and mysqld were coming up a lot during shutdown.

I had a MAMP PRO setup running those daemons at startup. Disabled them from running at startup in MAMP PRO. And voila, problem solved!

Check back in a day or so and tell us if this is working... Most everyone still see same issue a few days later and no matter what we try, it does not work in the long run ;)
 
Mid 2008 MBP. ML 10.8.2. 8GB ram. Boot up to usable, 2 MINUTES! Shut down 45 seconds.

Lion, boot up was under 45 seconds and shut down was 3 seconds.

Wife's iMac with Lion is the same, 45 seconds and 2 seconds.

If I wanted to wait this long to usable, I'd have stayed with Winders!:rolleyes:

Yes, the work machine on which I tried it is back to slow shutdown. I tried the daemon timeout change and stopping the apache and sql daemons on my home mac and it works.

Will be back with updates tomorrow if same works on work machine.

When did you do a clean re-install?

If you've never done a reinstall, that sounds about right for a 5 year old 5400rpm drive, with a 5 year old install thats been through multiple upgrades.

You obviously haven't been following the other threads about the slow shutdown time here. There is a bug in ML.

A clean install has nothing to do with it.

I did not read the discussion either but hopefully we will see that sorted next year when the 10.8.3 finally will be released..
