Hi,

I have rebuilt the 2.6.17, the speed is good. so, I don't know why 2.6.18 makes the RFCOMM socket communication slower.

Who can have a try to compare the speed using different kernel ?

Need your nice help. :)

if the 2.6.18 kernel is slower, then it must be something else. You
might wanna test with a 2.6.17 kernel.
