I am a graduate of Operations Research and Statistics option of a
Mathematics department .
All of your considerations are considered . It is so much apparent that ,
the cause is FreeBSD .

In my previous year message and in its subsequent messages , there are
sufficiently detailed information .


This message is caused from the following fact :

In previous year case , KDE used was a cause , but FluxBox was working fast
.
Now , I have installed 10.0 current . It does not have KDE in packages . I
have installed FluxBox .
It is not a few second slow : Many minutes to start Firefox , and activate
a menu of it  !

What is the point of measuring milliseconds when the difference is around
many minutes ?

PC-BSD installation ( it is a graphical installation after starting X ) is
taking many hours to reach 20 percent completion .
The same is for GhostBSD : Start it at night , at the next morning , it is
likely that it is not finished yet .


Then : WQhat will be measured ?

Linux installations are around 30 minutes .
Starting/Opening menus are instantenous : I do no have chronometer , but
everything is within a second .


Thank you very much .
