Hi,
I am just use the Bluetooth OBEX Object Push client (0.99 beta1).
====================================
Host:
 Vmware 5.5
 OS: Suse 10.1
 bluetooth dongle: 1.2
 File pushed: testpkg whose size is 137956B

Target:
  Nokia E61

  kernel version: 2.6.16.13-4 (built from Suse 10.1) about 11-12s   kernel
version: 2.6.16.13-4 (rebuilt from above) about 11-12s
  kernel version: 2.6.17 (built from kernel.org)  about 11-12s
  kernel version: 2.6.18: about  145s
  kernel version: 2.6.18 with mh4 (built with the patch from bluez):   143s
146s

Too terrible!!!
====================================

using other RFCOMM applications, 2.6.18 is slower too.
