I posted this in freebsd.question earlier and wish more people may see this=
 and make comment, but got no answer. Now narrow to performance group.



 It looks like not just X server is slow on 10.2-R, other servers slow too =
and take a lot of CPU.forefox is play music from youtube, while thunderbird=
 connected to imapd and doing nothing.
Those services take less than 10% total CPU when running 8.4 / 10.1.
Is something under 10.2-R needs to be tuned for performance?=20
or this hardware combination cause 10.2 -R not working well.
Some hardware information is toward the end of this email (in the original =
part).
