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 . Mehmet Erol Sanliturk
