Hello,
I have looked into this further but old firmware turned out to be the
problem.
Now that they all are running the 4.2 firmware the performance is fine
on all the different DTUs.
Maybe I did not noticed the old firmware because utfwload does not seem
to report this information for all DTU's
bash-4.0# /opt/SUNWut/sbin/utfwload -a
3.0 janmaat 192.168.1.202 P8-FS.00144XXXX63 4.2_77_2009.10.19.17.01
bash-4.0# /opt/SUNWut/sbin/utsession -p
Token ID Registered Name Unix ID Disp State
------------------------------ -------------------- ---------- ---- -----
Bull-CP8_TB60.000077f73eXXXXef ??? janmaat 3 EAU
Bull-CP8_TB60.000077f73eXXXXfa ??? user1 7 D
MicroPayflex.5002faaf00XXXX00 ??? user2 4 D
pseudo.00144fXXXX85 ??? ??? 5 EAU
pseudo.00144fXXXXbe ??? ??? 2 EAU
I thought utfwadm -a would give me at least 3 lines with firmware
information instead of 1.

I would look into the packet loss differences between these DTUs, and
if found, investigate differences in the networking infrastructure for
them.
The blocky updates only happen when the network drops packets.
Except for things like video, you should not be able to notice
differences in speed between these units, given equivalent networking
infrastructure.

Interesting thought!
I run SRSS 4.2 on SXCE build 127.
I notice some performance difference between SR 170, SR 270 and the
SR 2 FS.
The 2 FS works like a charm even video is handled pretty well.
The 270 works fine but noticeably slower when dragging windows and
playing video.
The 170 has a blocky screen build up and is the slowest of the three.
I thought it had to do something with de X extentions which are
better supported on faster hardware like the 270 and 2 FS.
But I can not remember the 170 being this slow with setups I used in
the past.
If the 170 is forced in a low bandwidth mode I am sure interested in
changing this.
