Does this problem effect only certain types of hardware, such as the new core 
i7 systems?

the machine i exprienced this is old macbook black that use core2duo. it was 
produced
in 2008 and osx version was 10.6. (without 64bit kernel support)

i don't know what is the problem exactly. in fact, my mac is always slower then
other's one regardless of machine. the combination of softwares i am running may
affect this.

i always run: firefox, thunderbird, xcode, interface builder, microsoft 
messenger,
xchat-aqua, activity moniter, python, keyremap4macbook, baram (custom IME), 
Terminal
wth Visor from SIMBL, XAMPP, ssh

if you want, i can retry to occure this problem and suggest a link to download
defective binary and sourcecode of my project.

Thank you for attention. its about 6 month wating ;)
