Ok, now I get:

   wrote 85144 byte from file main.elf in 9.609000s (8.653183 kb/s)

But I still think it's slow. When I write the same image to a STM Primer 
using RFlasher 7, it only takes ~3 seconds.

I also tried to use OpenOCD's RLink interface: 7.241484 kb/s. Much 
slower than the native RFlasher application.

BTW:  I also had a "too many retries waiting for DTC status" problem 
with OpenOCD's RLink interface.  Setting the retry count to 10 in 
rlink.c:526 fixed the problem (maximum used was 7). I'm using a cygwin 
build on Windows XP SP3.  Could you fix that in svn?
