[Bluez-devel] About the kernel 2.6.18

[-- Attachment #1.1: Type: text/plain, Size: 718 bytes --]

All,

   My oepnsuse 10.1 with the default kernel 2.6.16.13-4.
   When 2.6.18-mh3 released, I rebuilt and updated the kernel to 2.6.18 and
then patched it.
   When Holtman released the patch for handling multiple l2cap connections,
I patched the new kernel .
   But at last, I found that the speed of  the OBEX pushing and other Rfcomm
socket communications is slower than the original kernel.
   Then I rebuilt the 2.6.18 without the 2.6.18-mh3 and the patch for
handling multiple l2cap connections, I found it is still slower.
   So I think the patch is not the reason.
   But what makes the bluetooth communication slower? The new kernel version
2.6.18?

   Waiting for your 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.

Hi,
  I have rebuilt the 2.6.17, the speed is good. so, I don't know why
2.6.18makes the RFCOMM socket communication slower.
Who can have a try to compare the speed using different kernel ?
Need your nice help. :)

do you have a nice and simple test program and some results of your
testing. I like to run it by myself.

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.

This means that ~1000bytes/second are transferred. I am using 2.6.18 with =

ppp-via-rfcomm and it does get me at least 45kB/second (3G/UMTS speed), with
a sony-ericsson k600i as target, so there are configurations where it still
works fine.

Because Vmware I used, so I don't think it will make effect to the result.

Never done any tests in that direction but if you use a linux running in a 
virtual machine you can expect large differences in all HW / I/O related 
benchmarks. To get any useful results you have to use a native 
installation. Tests run in a virtual environment are absolutly 
meaningless.

since you are using VMware. Which is running the 2.6.18 kernel. The host
or the guest operating system. This could be bottleneck in the USB part
and not Bluetooth.

[Bluez-devel] About the kernel 2.6.18

[Mingfan.Lu]

[-- Attachment #1.1: Type: text/plain, Size: 718 bytes --]

All,

   My oepnsuse 10.1 with the default kernel 2.6.16.13-4.
   When 2.6.18-mh3 released, I rebuilt and updated the kernel to 2.6.18 and
then patched it.
   When Holtman released the patch for handling multiple l2cap connections,
I patched the new kernel .
   But at last, I found that the speed of  the OBEX pushing and other Rfcomm
socket communications is slower than the original kernel.
   Then I rebuilt the 2.6.18 without the 2.6.18-mh3 and the patch for
handling multiple l2cap connections, I found it is still slower.
   So I think the patch is not the reason.
   But what makes the bluetooth communication slower? The new kernel version
2.6.18?

   Waiting for your help;
