Many thanks for the detailed answer :^) Yes, I'm currently using HDD in my 
main PC and plan to buy SSD, but on my MacBook Air I also noticed a slight 
delay during Akonadi startup, I think that your script will help me. 
Apparently it's a disease of Akonadi.

About fragmentation: 
in my home directory stored a lot of git projects, which consist of hundreds 
of thousands small files, I think that they are the cause poor performance of 
my HDD. Can help me moving git projects to a separate logical partition?
