The problem is persisting over 9.1 and 10.0 current . My opinion is that , it is NOT related to KDE only . After X is started , any desktop is behaving very slowly . This is also visible in PC-BSD and GhostBSD . I am reading about very much slowness in some messages , which I suspect that , their problem may also be caused such an imbalanced memory chip placement . This problem is making FreeBSD unusable in such computers . The Linux distributions are NOT exhibiting such a slow behavior , and also Windows 7 is NOT affected . It seems that , in some memory management part of FreeBSD is badly affected such an imbalanced memory chip size placement . Thank you very much . Mehmet Erol Sanliturk
