I have changed HDD (WDC WD10JPVX-75JC3T0) for SSD (WDS500G2B0A) in my notebook and found that it loads at the same speed (not faster as I was expecting).

Why?

I copied partitions 1:1, may be I also need to change some settings?

By "speed" I mean cold boot time.

Here is part of dmesg output:

As you see, it does nothing for 90 seconds. What does it do?

I had swap partition defined in fstab. I didn't create it on SSD.

Solved according to this link https://ubuntuforums.org/showthread.php?t=2325129

Now it boots instantly.
