Boot time - Sleep time /Mbp/ What a difficult problem!

I do not know why but I am not sure that everything goes ok with my new mbp(early 2011).
Here is the specs: quad core 2ghz-8gb ram-256 ssd.

- It takes about 30 seconds to boot and log in the osx environment. Is it normal? Any other user to tell how much boot time takes in new mbp, especially with ssd disk?

- It takes about 15 seconds to go to sleep mode from the moment I select this option from ma menu. Is it normal? I think it is too much.

I suppose that something goes wrong. A setting to be adjusted or something to look at it.
Can you please help me to find out what causes these delays?
 
There is something wrong. After the recent EFI update, my MBP 15" 320 intel ssd boots up in around 10 seconds. Before that it was maybe 15. Also sleep mode is instant.

Which model and OSX version do you have exactly? Did you install all the latest updates? Is the 256 ssd OEM or a third party model?
 
I have 10.6.7 installed, new efi installed yesterday. Ssd is from apple, it was built to order mbp.
I cannot explain what happens.

Some programs make sleeping take forever. If I have the MSN messenger app open, sleeping takes 30 seconds or more as it was poorly written and the signoff takes forever. If it is off, sleep is instant, and I've got a platter hard drive.

Try closing all applications first, see if the sleep problem persists.
 
As said before something is wrong...

I just did the firmware update for my momentus XT and reset the pram and SMC, it now only takes my 2011 13" i5 18.5 seconds to boot from the time i hit the power button until OSX is loaded.

A full SSD should be much faster than what you are experiencing.
 
Try these commands in terminal.

For the boot:
sudo chown root:admin /
sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches

For the sleep mode:
You can make the system not to backup ram memory to hard drive every time you go to sleep, so the system goes to sleep faster. The only problem is that if the system completely loses power (if the battery is fully empty for example) the system will normally boot and you will lose the session. Older macs has this mode by default, but some years ago apple started to use this slower safer mode. But you can change it with that command. I you want to go to the normal safe mode just change the 0 for a 3.

sudo pmset -a hibernatemode 0

That would make your hibernate and boot times super fast.

Also try to reset pram and smc.

Tell me if it works ;)

You should probably let him know what that last command does before he does it. So he's not left wondering why his laptop no longer deep sleeps when it loses power. ;)

I did all these but the boot and sleep times are the same.
Should I type something in terminal to return to a previous state about hibernation, now that I tried it?
 
sudo pmset -a hibernatemode 3

-or-

sudo pmset -a hibernatemode 7

If you have secure virtual memory enabled, use 7.

Also, if you really want to squash any possible software bugs and eliminate that variable, I suggest you back up your files, wipe your drive and do a clean install of OS X.

Slightly OT: Is there a reason why you don't just close the lid and walk away? Then, sleep time matters not. I'm thinking you use a mouse and keyboard with external monitor?

FWIW, My C2D MacBook sleeps instantly. Boot time is another thing, but I almost never reboot.
 
I am not using external monitor & keyboard.
My old c2d sleeps instantly too. My new superduper mbp does not!

The boot time I mention here is when I start the machine after a shutdown. Not about recovering from sleep mode. This is almost instantly.

Where should I look now?
It seems to be an osx/software problem.

Two thoughts:
- boot time and sleep mode may be related to each other.
- if there is a kind of problem, then it may affects me in my daily mac tasks without even realizing it. Lets' say that maybe mbp works slower than it could run in a normal(non problematic) situation. I come from a c2d mbp, so in any case I see speed overall. But this is not the case. It is a pity this new machine not functioning in full speed.

So, I would like to search for a solution for these 2 problems. Maybe the solution for these things unfolds an even faster osx use for me either.
 
I copy from here
https://discussions.apple.com/thread/1051695?threadID=1051695
for 2007's mbp:

"The added time for sleep is simply due to you having more RAM. As part of the Safe Sleep procedure the contents of RAM is copied to hard disk to preserve its contents again all possible power related issue. This however means that the more RAM, and the more RAM that is in use, you have the longer this will take."

Could this be the problem? In early 2011 mbp?

Is it possible the bigger ram(8gb) to slow down sleep?
Boot time?
 
Yes, 8GB will cause a "delayed" sleep, vs something like 1/2GB, because it has to create an image of the entire 8GB. However, with an SSD, it shouldn't be that long.

Like I said before, if you have the time, try a clean install of OS X. That will (or should) eliminate any software faults and will leave only hardware behind.
 
My login screen shows 'macbook pro c2d' .
Is this ok or I should see something else?
(i migrated my settings from my old c2d mbp if this is the case)
 
I think therein lies your problem. When setting up a new computer, I can strongly recommend NEVER migrating all your settings/information from your old computer. Back up only the files you need, personal documents, etc, as often times, migrating will carry over old/create new problems for you.

Once again, I suggest a clean install of OS X.
 
I have a 2011 17" macbook pro. I have 8gb of ram. Before the last apple update it went to sleep instanctly. Now it takes a lot. At least 20 seconds or more. Anyone noticing the same??

My iMac has 8 GB and sleeps instantly.

You mean the transition from 10.6.6 to 10.6.7?
I put 10.6.7 straight away when I get the machine so I cannot make a comparison to the previous state.
