I’ve been able to experience the results of implementing Workspace Environment Management into a Citrix XenApp and XenDesktop environment. I was easily able to obtain at least a 50% reduction in logon duration.
In 2012, I started my pursuit of astrophotography. Let’s just say the results of M42 – The Orion Nebula were not very impressive.
Over the course of 5 years, I continued to try out new techniques and learned a lot about signal-to-noise ratios, imaging histograms, Bahtinov masks and more. I continued striving for better results and am glad to say, the my work is finally showing positive results.
All of the effort is starting to show some very good results.
I find that astrophotography gives people a “Wow” feeling; so, let’s change topics to something that creates the opposite feeling: Logon Time.
The title is correct. We can improve user logon time by implementing PVS accelerator in XenServer 7.1.
This actually makes perfect sense.
We already showed that PVS Accelerator drastically improves VM boot times because portions of the master vDisk image are cached locally. Booting a VM equates to roughly 80% reads and 20% writes. VMs using the same image are reading the same blocks of data. Due to this similarity, we are able to see huge network utilization reductions by using the PVS Accelerator cache. These reductions in the network utilization translates into faster boot times.
A few times a year I get addicted to Xbox. Once the kids go to sleep, I can easily spend hours playing Mass Effect, Fallout or Assassin’s Creed.
The games are wonderful and immersive, which is why I spent over 100 hours playing Fallout 3 and another 100+ hours in Fallout New Vegas. Unfortunately, I’ve experienced some annoying things with these games. I’ll be in one of the final battles of Mass Effect 3 against the Reapers when the game starts stuttering. Do you know how hard it is to aim when the system stutters?
Game stuttering, system stuttering or application stuttering is a great way to severely hurt the user experience. How can we reduce app stutters? We need to look at the underlying reason for the stuttering and figure out how to correct.
Network latency and packet loss is a big reason why users might experience stuttering in an application. If a packet gets lost or a packet times out due to high latency, that packet must be retransmitted. Retransmissions take time. And if you experience a lot of retransmissions, you experience a lot of application stutters.
We’ve already seen how Citrix’s Adaptive Transport impacts
But what does it do to the application experience? See for yourself
