I would appreciate it if someone could share their experience with zero clients & CPS. I am primarily interested in:
- What model(s) have you deployed (or are considering/testing)?
- How are you serving the client and over which protocol – Vmware View/PCoIP, RDS/Terminal Services/RDP, Citrix/ICA?
- Do you have any issues with USB redirection of scanners/microphones/signature pads/fingerprint scanners, etc. attached to the zero clients?
- Any "gotchas" in general...?
Thank you in advance.

We use Wyse P20 and P25 zero clients to connect to VMWare virtual desktops. We run CPS as an installed app, as opposed to streaming or thin app. We use usb dictaphones, which work well, providing you use the right firmware. I am certain microphones and headphones would work well. However, scanning is slower, especially multi-page scans.
One gotcha I have encountered is the firmware issue. We have to downgrade new P25's that come in as the newer versions of the firmware does not work with Olympus dictaphones.
Otherwise, they work great. We can deliver lossless video to two HD monitors. No lag and very versatile. We get the same performance with the VMWare Horizon Client running on a PC. Users can securely log in to their desktops wherever there is an internet connection.
Let me know if you need any more information.

We use HP t310 with a few Samsung NC zero clients spread around. The zeros drop into VMware Horizon 6.2 virtual desktops.
We've been very pleased with the results. When you need to do an update, you simply update the master image, then push it out to all your desktops. Generally, this is done at night, as it's very I/O intensive.
We have a few physicians using Philips Speechmikes, used with Dragon, which redirect well. I haven't seen any of the issues that halloman above me has seen, but your mileage always varies with these things.
Sadly, I don't have any experience with USB signature capture, or fingerprint readers at the moment.
The main gotcha you have with Horizon is that if you have a problem with one user, it's likely that you're going to have that same problem with all your users.
We do maintain physical computers for our scanning PCs, due to the speed issue that halloman mentioned.

Thank you Ron. That was pretty comprehensive information. Do you have gig to the desktop? Seems like CPS works pretty well in your environment. We have mostly thin clients and PCs, using Terminal Services, and are constantly hearing complaints about performance. We've tweaked the wrapper.conf, done obs term archiving and the server specs well exceed what GE recommends. My hunch is that the encounter forms impact the end user experience the most.

I would love to do this someday but the problem has always been Nuance. Are you using Dragon Naturally Speaking, Ron? If so, which version (DNS Medical Edition 2 or cloud or other). Do you have the ability to use templates? Our docs can say "Insert normal Exam" and it will spit out a paragraph which can then be edited to the patient's specifics. That seems to always be a problem with cloud
Thanks

We don't use Dragon but I think it would work fine. It works well with USB microphones and headphones, so I don't see why it wouldn't.

As all our servers and desktops are virtual, and live in the same server rack, they actually share data at speeds of at least 1GBs, sometimes more depending on the configuration. We still get complaints about CPS running slowly, though. At this point, I think the bottleneck is the application itself.

Thank you Ron. I wish there was a single document/thread that outlines CPS performance improvement tips and tricks - everything consolidated on a single page/doc, from hardware infrastructure/architecture perspective and from software. I know there's the hardware calculator for 12.2 and the new service packs are supposed to automatically tune the performance based on certain parameters but I think information from the community could nicely supplement all that. Maybe such a thing exists and I just don't know about it :). Having some idea how long does it take (and perhaps benchmark vs how long GE says it should take) to launch the app, open an encounter, etc. on average would also be helpful.
