I am going to revive this thread a little. Since I last wrote, I replace my feeble server with a more robust 4 way v40z last week.
I have CPU cycles, network bandwidth and memory to burn. We have noticed some odd behavior with the DTUs. Initially, things were not much better, the managed switches showed very low network utilization on the DTU ports and server CPU utilization was nigh-zero. After a few days of uptime, one or two of the heads on the triple head displays started refreshing very quickly, and those ports on the switches showed much higher, ~50%, link utilization. Sometimes the heads would revert to slow refreshes. I haven't figured out the pattern of when they will behave a certain way. There appears to be two refresh modes: 1. Low bandwidth refresh which is slow and updates blocks across the screen top to bottom and left to right within each row, taking more than a second. This makes scrolling in a browser/PDF/OO Document/gnome-terminal/etc. a painful task. 2. High bandwidth refresh which is fast and consumes the ethernet link, smoothly refreshing the whole screen in less than half a second. I seem to recall that 4.1 ran in "high bandwidth" mode quite often but 4.2 prefers the slower mode. Changing the DTU to the 4.1 firmware had no effect, so I can only assume it is SRSS which is making these decisions. Assuming (naive, I know) that this is how SRSS operates, is there a way to coax it into the "high bandwidth" mode permanently?
