Does anyone out there have CPS 12 installed on a 2008 R2 Remote Desktop Server? We get a lot of complaints from our users that it is much slower than CPS on a fat client. Our server specs exceed the minimums given by GE. Any advice would be greatly appreciated.
Thanks,
Gary

Yes, we however do not have that issue. What are your specs and how many users are on it at once?

IE9. We initially installed on a 2012 and had major issues with the ie10.

All of our terminal servers are virualized with 4 intel xeon x5650 processors, and 15 GB of RAM. Users range from as little as 8 on a server to upwards of 25 on one of our busiest servers.

Yes. We use 08 R2 RDS. I can tell it's noticeably slower than CPS 2006 through CPS 10 on our 6 year old 2003 terminal servers with 35 active users per server. Currently we're running about 25 active users per TS. One of these days I'll probably look into it.
We don't have any fat clients set up so unfortunately I can't compare.
I can tell you that for us, the print spooler really consumes excessive CPU when users log into the terminal server. I've not had a chance to really dig into it though.

With ours, it doesn't seem to matter what specs we throw at it, we hit 9 users and then it goes south in terms of performance. This was the same on 2008 servers before and we have kept ours to 6 users on slightly lower spec RDS servers and get an equivalent experience as local installs.
We kept Schedulers and Front desk staff on local clients for attachments and performance as we saw drastic difference when using scheduling and with using two monitors in the RDS world.
We haven't been able to really find any cause for this that we could resolve.

Correct, i have about 6 users per virtual terminal server. It might be that the network flow and data communication to the server with to many users on the same machine might be the problem, you might want to check your network performance to see what it looks like. You also state, they are virtualized, make sure not sharing any like resources between multiple virtual systems. We are on stand alone Servers for users that are more then 6, and only virtual on those that are under 7 users. I have not noticed a performance difference from a standard system, however, it is way slower compared to a FAT client on SSD drives.

Our RD environment is setup with Generic user accounts. There are under 40 connections for exam rooms but these are generic AD accounts that are used every time for a particular room. This reduces the mess created by Windows profiles.

I just checked our server specs. We're virtual (VMWare) on AMD gear. We have 2 Opteron 6376 CPU's per vhost and 16GB RAM.

We also use generic user accounts on our terminal servers for our exam rooms. The slowness that our users complain of can happen with only a few users logged in. Our virtual environment uses 10 Gig iSCSI with a couple of large RAID 10's. We have lots of spindles, so we know it isn't hardware related. Network utilization is very low. Have any of you gotten complaints from reception on slow printing of superbills and receipts?

I run EMR 9.8, not CPS but as far as superbills are concerned, there has been a known issue printing superbills on Citrix (which is basically the same as RDS) for a long time. I think they just fixed it for us in one of the latest service packs. I would imagine that the same bug probably exists within CPS.

SLVH,
As far as your issue with the print spooler, if you allow redirected printers and there are a bunch of printers on the client computer, this could definately make the print spooler use up a bunch of resources on login.

We do not allow RDS redirected printers. One of my colleagues started testing https://support.microsoft.com/en-us/kb/2666508 yesterday actually, even though it doesn't seem to directly apply. We don't have an objective baseline so unfortunately will not obtain any useful stats, but so far I'm hearing that it "feels" improved.

We do not redirect printing on the terminal servers either. We install the printers locally on the RDS which sped up printing on the chart side of Centricity.
