Hi,all,
the following is my test result in a real machine:

Memory: 1G DDR 533

Hard Disk: 5400转 8M cache

CPU: PM 1.86G 2M cache
==OS: suse 10.1
==kernel 2.6.16.13-4 and 2.6.18
==Files: 2 file,one is 1M, the other is 77k
==Bluetooth OBEX Object Push client (0.99 beta1) to push file
==result:

Ave. time

Kernel 2.6.16

Kernel 2.6.18

First File (1M)

68 s

115 s

Second File (77k)

5 s

9 s

~15Kps in 2.6.16
~8.5Kps in 2.6.18
still slower.
