Martin,
I have done some tests like you mentioned.

A real machine (P4 3.0G+1G RAM)
Debian Linux (original kernel 2.6.8)
Bluez 3.6

I have rebuilt the kernels in debian way:
2.6.16.13-4 from opensuse 10.1
2.6.17 from kernel.org
2.6.18 from kernel org
2.6.18-mh7 (with the patch mh7 from
bluez)

The speed of OBEX is similar, but still low. about 5Kps. < 15~30 Kps (Your
results.)
I don't know why.
The configure?
Could you give me your .config file when you build the kernel.
Thank you very much.
