After installation of TLP I have notice a increase of 5 up to 7 seconds on boot in xubuntu

I have intalled TLP on xubuntu and I notice a increase of time btw 5 up to 7 seconds on boot time according dmesg output and I have now some ACPI Warnings on boot, I'm attaching my dmesg output and my grub file. What can I do to reduce 5 or 7 sec. on boot time? How to remove these warnings on boot? My kernel is 3.11.0.26, [ 26.568413] this is my boot time.My laptop is DELL inspiron 3521 BIOS version A12. Thanks for now Vladi.
