Hej Angela,

latency counts double in RDP and related technologies.
Said that, explained with an example:
Action : Indian user klicks mouse > 150 ms > On Server
Reaction : Server > 150 ms > Reaction to mouseclick on Indian users Screen

Ways to work around?
Maybe SpeedScreen Latency Reduction is an option.

Another option is to shorten the distance between User and Server
- by building a new (small) farm, include as own zone into the
existing structure
- by relocating the whole farm (guess that's unlikely)

hth, Marcus

Hi

Running a 6 x Server XenApp 6.5 farm. I've got users connecting in from
India and they are complaining about performance being slow. Slow
saving documents and slow screen refreshes. The Citrix Server and
Windows File Server are in our main site in Australia so there is no WAN
traversing.. My gut feel is that its simply a latency issue but was
hoping for some suggestions for troubleshooting.. Here is the ping
response from India client to Citrix Server:

I've deleted the users profile and they are running the latest ICA
Client.. Any other ideas for troublshooting?


Thanks
Ang

Use a multi-layered approach.



I use a Skydog Router. It is inexpensive and very powerful in what it
can do.

Safe Eyes software is very effective.

OpenDNS is pretty good.



I'm sure you know, nothing will ever be 100%. So let them know in no
uncertain terms, up front, that you WILL be monitoring what they are
doing, and that they should NOT have any expectation of privacy when
using anything on the internet. That way there are no misunderstandings.

Greetings

We do Emergency Foster care and are for the first time getting an older
child that needs access to the Internet for school.

I have let the other kids just get on line and didn’t worry, but now we
are getting an 11 year old and I need to figure out

how to lock it so she cannot go to places she is not allowed, in the
past, with my own children I used ‘Net Nanny’.

Any ideas on what is current and works?



Thank all



Cheers
