As many of you saw, XenApp and XenDesktop 7.17 was recently released. And again, there are statements saying that due to optimizations in the codecs, bandwidth usage rates dropped again.
Is it just me, or does it seem like every few releases Citrix finds ways to further reduce bandwidth consumption. When 7.13 came out, there were statements saying bandwidth utilization dropped. And in 7.17, we are hearing similar remarks.
I wanted to see how true this was, so I ran my own simulations. I decided to run tests against the 7.11, 7.12, 7.13, 7.14, 7.15, 7.16 and 7.17 releases.
I know, the lines do get a bit jumbled, but you can see each simulation ran similar workloads as the rises in usage all appear within similar time periods.
To make it easier to see the overall bandwidth reductions, lets switch to a bar graph.
Now you can easily see 3 distinct groupings of data:
- Group 1: 7.11 and 7.12
- Group 2: 7.13-7.16
- Group 3: 7.17
So it is true, 7.17 further reduces bandwidth consumption.
