boot time extremely long

The other day I turned on the computer and I noticed that it took around 15 minutes to boot. First I thought it was just that particular time but it turns out that every time I turn off and turn on the computer takes that time more or less.


I have a MacBook Pro 2011 15''.


- Searching the forum and internet I found that sometimes this problemas are because hardware failures. I made a hawrware analysis (Command + D When turning on) but did not detect any problems.


- Then I thought it might be a software problem and updated the version of the OS from Lion to Mountain Lion, I installed everything without problems but I still have the same problem.


- I also done a Safe Boot and run the command fcsk -fy in Terminal.


- I also tried to clean the ACL


- I reset PRAM


I tried to read the log file of the boot but really I don't understanded well, but i found that there is a big time interval between theese to lines, maybe the problem is there:


11/07/13 19:50:08,000bootlog[0]BOOT_TIME 1373583008 0
11/07/13 20:09:55,000kernel[0]PMAP: PCID enabled



What options do I have?


thank you very much

MacBook Pro, OS X Mountain Lion (10.8.4)

Thanks Carolyn, but I already tried that.


I have no elements on startup items.


Also I have 70% of free space in the disk.


Maybe I am wrong but I think the clue might be between theese to events when booting, because there ir always a gap of 20 minutes between them, and I think that are the 20 minutes long that my MB last to boot.


Again, 20 minutes between events.


12/07/13 10:56:49,000 bootlog[0]: BOOT_TIME 1373637409 0

12/07/13 11:06:48,000 kernel[0]: PMAP: PCID enabled


Any clues?


Thank you very much.
