Very few (enterprise) switches handle udp buffering well. This limits
the rate to prevent overrunning the switch. In essence, it's granting a
lower rate. At higher rate, switches tend to drop the udp stream.
Ironically, the more expensive the switch, the more apt this is bound to
happen. Cheap switches just forward stuff on, they never buffer.

Hi Craig, you seem to be referring to lore written up in section
18.11.4.1 of
http://docs.oracle.com/html/E22661_15/Troubleshooting-Performance.html
where it mentions "The X server is allowed to send at a certain specific
rate granted by the Sun Ray Client".
So, does setting the hires_tick on the server ultimately cause the Sun
Ray Client to 'grant' a higher rate? Or does it affect only the server
so that it delivers data in a smoother (less bursty) fashion ("fill,
drain, fill, drain" instead of "fill,fill,drain,drain" where the switch
can only take so many un-drained fills before dropping a packet)?
Assuming the latter, is it more preferable to have a switch which can
handle the buffering, or to set the hires timer?
thanks,
thanks,
David.
