I’ve learned that a Windows Xp to Windows 7 Migration is tough for loads of customers as the tools they mostly use aren’t easy to work with. Check out this video about an In-Place migration of Windows XP to Windows 7 with VMware Mirage.

Performance/Stability issues when using View 5.1.2 Agent on physical machine based desktops

without comments

When visiting the VMware View Download page at today I’ve got a notice about a new knowledge base article which was published back in December 2012. If you’re using the View Agent on a physical desktop computer to get remote access to it you might face some performance issues or will have an decrease in stability. This symptoms can only be seen on physical desktop, NOT virtual desktops in a VDI.

Only the agent version 5.1.2 seems to be affected.

You want to tell me PCoIP performance is bad?

with 7 comments

Update: I want to clarify that I of course know that network connections all over the world are different in speed, latency and packet loss. My video only shows that my ad-hoc connection from Europe to the West Coast just works well and the video/website mentioned in this article could give the readers/watchers/listeners are wrong impression of PCoIP.

This week I was really surprised about an blog article I saw linked on Twitter. In the article/videos the author shows a virtual desktop connected over PCoIP from San Francisco to Ottawa. For more details on the scenario please check the article and also listen to the speaker in video. He said: “Definitely much much worse than ICA was…”. Well the “real world” scenario as he describes it looks really strange to me. Ok, he’s connecting from a hotel internet connection (which is mostly crap, but in SF?) via VPN to his data centre but only on one continent with a distance of approximately 5100km (Maybe the cable is going a longer way…). I know PCoIP and is has definitely a much better performance on the WAN and I checked it. This is my real world example: My connection is from my home office’s DSL line through the VPN to the data centre in California.


A ping from my local workstation to the View Manager Server looks like that: (Doh! 382ms)

64 bytes from icmp_seq=2 ttl=242 time=382.313 ms
64 bytes from icmp_seq=3 ttl=242 time=382.777 ms
64 bytes from icmp_seq=4 ttl=242 time=382.545 ms
64 bytes from icmp_seq=5 ttl=242 time=382.215 ms

And the result looks like that:

I think this is great for an overseas connection and watching a video, hah? Sometimes it hangs for a short time but 382ms!
