We just flashed a S10 with ThinOS 7.00.30 and have been testing with RDP and ICA. Well RDP is MUCH better than it was, we’re using Youtube football movies to test (lot’s of movement) and RDP is very very acceptable.
So we then configured the unit for ICA, and well…..to be honest it’s awfull. It’s much worse than RDP!!! Did an A/B test with a Windows XP ICA 12 client on a PC to the same farm, same server, same IE8 and that performs super smooth. So what’s wrong with the ICA performance in ThinOS 7 on the S10? I assume Wyse lifted both RDP and ICA to the latest levels, RDP 7 and ICA 12? Or am I Wrong? It’s not the hardware because RDP performs well.10. December 2010 at 14:34 #19561
S10 doesn’t support any kind of multimedia redirection since it has slow enough CPU. Try V10L(LE), C10LE, R10L – you’ll see very good results.14. December 2010 at 10:51 #19571
Well that might sound logical but it’s not. Because running RDP 7 with multimedia redirection works just fine on the S10. Flash is pretty fast and smooth. If the S10’s wouldn’t support multimedia redirection / HDX then Wyse wouldn’t have put out the ThinOS 7 update for it. It’s an ICA problem.
ConfGen: do you have any idea? (Since you have good contacts within Wyse.)14. December 2010 at 11:02 #19572
It’s the ICA that is not performing ok, while running on a Citrix XenApp 5 on Windows 2003 R2 BUT ALSO XenApp 6 on Windows 2008 R2 on a S10. XA6 should run flawlessly. However RDP 7 works fine and that baffles me because if it would be the relatively light hardware of the S10 than RDP 7 would be slow too, right? Aside from running slow, flash movies thru ICA also crash after about 30 seconds or so and closing the browser can take more than 1 minute.
Flash movies are becoming more and more an issue for our users since eg Youtube contains a lot of instruction and educational movies.14. December 2010 at 11:09 #19573
There’re things that run on S10 but NOT supported (for ex. RichSound on WTOS 6.X.X) The situation maybe similar in your case. Take a look at the list of features OFFICIALLY SUPPORTED in S10 WTOS 7. You can raise the case if you find HDX MMR (RDP7 MMR) there. But – from the experience – you really need V, C or R classes to have good MMR and Flash14. December 2010 at 19:54 #19600
Of course I understand that V10L or C10LE is better and faster. But we have lots of S10’s in our installed base. And Wyse 1200’s too. Of the latter I can explain to the customer that they are just too old. But not for a Wyse S10. I looked for the official list but didn’t find it. Where can I find that? (Google didn’t help).15.

Thin Clients Comparison chart on wyse.com and the same for thin clients OSes I think17. December 2010 at 2:19 #19644
Unfortunately there’s nothing on ThinOs 7 on the Wyse site. The datasheets are still 6.x, mentioning RDP 6….I will post a support call to Wyse and also in the Citrix forums. We also have old Neoware E100’s with XPe SP2 and installed the 12.1 client from Citrix: performs as a charm! What a bummer, seems neither Citrix nor Wyse can get their ICA client for Linux or actually their non- Windows clients to support flash right. Can’t explain this to customers! Will test on 6.5x see what that does.17. December 2010 at 7:59 #19647
well, you are talking about quite different thing – WinXPe client – it’s like comparing truck and passanger car. Wyse uses pure Citrix recievers both on Linux and WinXPe and you’ll get everything you have on E100 on say C90LEW(and even more I think since it has hardware media chip), while ICAHDX reciever for WTOS is Wyse development. It is very good on V10 and newer. I tested both media and flash – very good. And I think that E100 doesn’t have 300Mhz CPU and costs much more than S1018. December 2010 at 2:08 #19653
Well, I think i discovered something that can cast more light on this subject. I found that – due to licensing issues – you need a TCX license on the thin client in order to enable Flash HDX redirection on ThinOS. Of course we don’t have that. I installed an evaluation version of TCX Server 4.01 on one of the servers. But now it appears I also need a license key in wnos.ini to enable it on Thinos. No eval. license key anywhere on the server side! No options to get one either. Any ideas?18. December 2010 at 9:11 #19654
TCX and HDX are doing (nearly) the same. In case of Flash, HDX is doing a flash redirection. While TCX is doing a flash accelaration.
The difference is that HDX is redirecting the flash data to a local flash player and displays is this way. TCX is reencoding the flash video in a motion JPEG, transferring it to the client and displaying it then.
As WTOS does not have a local flash player, there is nothing HDX can redirect the flash video to. Therefore the video will handled the same way as with TCX.
You will not see a big difference when using one or the other on WTOS (but you will see a big difference when using any Windows client with a local flash player – HDX is better here).
For TCX you only need a serversite license nowadays. Older versions of TCX needed a local license but no serversite one.
So, when you install TCX eval on the server there is nothing more you need. Should work out of the box for 30 days.
But as the S10 has not enough power to render motion JPEG locally it will not work fine as you have already seen.

Thx for the clarification ConfGen. Well I tried a V10L today and no more hanging. Video is fairly smooth. However I am experiencing problems with the sound. It keeps dropping out and when there’s sound the video stops. The session remains responsive though and I can select another piece of the video but the sound is messy. Doing the same thing on Windows XP SP3 on a pretty old pc without Flash redirection in the same network is fine though, no problems with the sound. Tried putting AudioQuality=low in the ini but doesn’t make a difference. Have a fully patched XA6 server with the latest (24/11) Citrix patch. However I am using 7.00.30 and I heard the latest version is .34. Is this a problem with the firmware? Or the config? Can I tune this?19. December 2010 at 15:12 #19660
Tell a link you are trying. I have just installed a XA6 server here and can test with different FW versions.

You could check this one out: http://www.youtube.com/watch?v=aTN89LxRBbM Another test I also do is Starting Google Maps and then zooming in to an area on the map until I reach Street View.
I have currently tested:
1. Windows XP SP3 on a PC with Online Plugin 12.1 (result: very good)
2. Windows XPe SP2 on a Neoware E100 with Online Plugin 12.1 (result: good)
3. Windows XPe SP1 on a Wyse S90 with Online Plugin 12.1 (result: pretty good, choppy sound however)
4. ThinOS 7.00.30 on Wyse V10L (result: fair, but very choppy sound)
5. ThinOS 7.00.30 on Wyse S10 (result: poor and unusable, crashes after 30 seconds making the browser unresponsive, very choppy sound)
6. ThinOS 6.4 on Wyse S10 (result: poor, but doesn’t crash, very choppy sound)
Pretty interesting is that the performance of ‘3’ is better than ‘5’. S10 and S90 share the same hardware platform if I am not mistaken. So it appears that it’s a driver issue. I also tested on 2X CCOS which is actually a Linux build. Installed or ran it from a USB stick on different pc hardware. Here I noticed that if the drivers were optimized to the hardware even a Youtube film like above would perform acceptably: on recent ‘fast’ hardware CCOS / Citrix would perform good. On underpowered hardware it wouldn’t. Try it with Windows XP on the same hardware and it always performs good. So this looks like a Citrix issue related to video drivers running on non-Windows (Linux) environments. I think Citrix still has some work here. Noticed that 12.x is not available on Linux or Mac. Well, maybe it’s tunable, maybe you need to adjust a couple of parameters.
I am very interested to know the result of your tests with different Wyse models / firmware.20. December 2010 at 13:34 #19665
Are you testing in fullscreen mode or just the original Youtube window?
I have tested today with C10LE and a beta firmware 7.0.1_109. In window mode the video was perfect. Same look and feel like on my PC.
