Excesive bandwith usage by vWorkspace

Hi,

I'm seeing this in some form also following the steps you posted.

Running in a window (1440 X 900 32bit) and EOP Xtream it ranges from 1.8kbps when idle up to 2.1MB/s! scrolling in the same folder.

Holding down the scroll down button in outlook (inbox has 4000 messages), the download meter gets to around 400 - 500kb/s.

Just adding a shape to a word document and moving it around seems to go over 1.0MB/s

I get next to the same results with EOP Xtream disabled.

This is accessing offsite using the SSL gateway

Accessing the RDS server directly using RDP uses less than half the bandwidth. - Thats with Aero enabled also.

LOL... to add watching a none-redirected flash video goes up to 10.1MB/s and pretty much renders my WAN connection to the desktop unusable until the browser is closed.

Dan.

No problem >:)

My environment is also running MR1.

wow! It's nice to see I'm not alone. Thank you for taking the time to reproduce it, I really appreciate it.

10MB/s ? aaaawesome :-)

I0m trying to figure out what is being transmitted using Wireshark but I still haven't a clue

I also noticed that the bandwidth used in a direct connection (without the RDP gateway) is less voracious but still a lot heavier than classic RDP.

By the way, all the workspace components are updated to the 7.1 MR1.

lol, On the LAN watching flash (no redirection), 26Mbps

I don't think this is a problem more of a "feature" of how it all works... Still an official explanation as to what's going on would be good.

I found a quite interesting clue

If I use the AppPortal (desktop integrated or not) to access a published  desktop I've got the high bandwidth usage issue commented above.

However if I connect to the same desktop using the "vWorkspace Client\  Remote desktop connection" tool, the bandwidth consumption pretty much  the expected (about 1.5x over classic RDS, but quite acceptable)

I configured both (the AppPortal and the "vworkspace rdc client") to use  the ssl gateway, rdp over ssl and eopxtream and without flash  redirection.

I also noted that the quality of graphics is much higher using the  rdclient than using the AppPortal (using the same experience and display  settings)

Now, It looks an AppPortal bug to me.

I've tried to replicate this but for some reason EOP Xtream didn't work for the RDclient... However bandwidth was lower but not by much... Despite EOP being disabled the GFX seemed a little better but again not by much.

The hi bandwidth issues I'm seeing are also effecting the web client.

Dan.

It sounds like there are two things happening here:

1. EOP Xtream enables RDP to use more bandwidth if it is available, so you get a smoother, faster response and a better user experience, but it should not be anything like a 10x or 100x bandwith increase!
   
2. It seems you are saying a big difference in bandwidth use between scrolling a browser in a full desktop vs. a single app in seamless windows mode, aka AppPortal? Please confirm here, and also raise a support case if that's what happens.
   

Hello Jon,

I noticed big difference in the bandwith  usage between a full desktop opened using the "Remote desktop  connection" and a full desktop opened using the AppPortal.

thanks!

Thanks. We're looking into this right now.

Same thing here, spikes up to 10meg...not good for WANs

Any updates?

Any updates? known causes to this?

Cheers,

Dan

We had a good 2 weeks working on seamless issues and nailed a lot of quirky behavior seen on Windows 7 access devices. The fixes will be in the next update to 7.2. If you would like to get your hands on a Release Candidate let me know please.

Jon

Cheers,

I shall wait for the final eagerly...

We are also started moving people to the App Portal (since RDP client bypasses the Connection broker leaving us with multiple sessions)

We've also started getting complaints about bandwidth...

Will put in supprot ticket about access to RC
