If so, do you know what version/release of gdb you used?
used Sourcery G++ Lite 2011.03-42
Have not noticed any speed issues, most of my testing was under linux
however.
I am running winxp, that has always proved fairly nippy compared to
vista anyway.
Delving into openocd logs, taking a -d3 on both pipe and tcp usage, I get
exactly the same commands being run for both when stepping over the first
line of my program, but in pipe usage lots of them take 100ms longer:
That 100ms may well be caused by the win32 version of select - win32
select does not support pipes so had to create a special version.
Check out the MsgWaitForMultipleObjects and you see your 100ms delay.
Perhaps this function needs tweaking.

If it's a code issue with openocd code, I would have thought you'd see
the same problem in pipe mode on windows, I know you said you never used
it much, but I find it's instantly noticeable, around a factor of 10
different in speed.
With all this playing around though, I've also found that openocd
doesn't shut down properly in pipe mode with eclipse, neither hitting
terminate not disconnect in eclipse will actually shut down openocd or
gdb, they just sit there hanging. I just have to resort to task manager
to shut it down. Maybe I'll just have to stick with using openocd as a
separate external tool still. Unfortunately I'm locked to windows for
using Altium Deisgner (my main role is electroncis design), and I just
get sick of trying to do too much in vm's.
Thanks,
Andrew
