Late 2008 slow boot

[strat71]

My mac boots slower than to expect.
When i press the power button it doesn't react right away and go to white screen as expected.
Mine stays black screen for about 5 sec,and then white about 7 sec before apple appears and then about 12-15 sec to desktop.
As you can see i have a okay fast SSD,that i have tested in a late 2009 mac mini with a boot time at 15 sec.
I have tried SMC and NV/Pram resets,boot without SSD and ram and it it still the same,so it is not disk or ram.
Has anybody else had that behaviour or know what causes this ?
I know its an old machine,but when OS X is loaded it goes all fine a fast.

Doesn't sound too outrageous to me. But do you have more than one OS installed? Check that the proper volume is selected in System Preferences -> Startup Disk.

With my mid-2007 MBP it's an instant on black, white and boot logo screen for almost 30 seconds, then login screen. SSD here, too. No peripherals attached.

When I replaced my Hd with an SSD it initially had a delay before booting.
I found it was because my old HD was selected as Startup Disk. It would look around for it for a while and then go to SSD.
Once I changed the startup disk under Preferences and Startup Disk, the delay was gone.
