Citrix Farm Design and recommendation

I have got a new customer where they have two citrix farm with two different versions.
I have attached teh screenshot of the design doc.

Customer also raised few queries like this

Users often can launch an application from WI but after a period of time sometimes they receive an error when trying to launch another application.

 Installing Citrix on new London Servers sometimes fails.

If stopped sometimes IMA Service will not start on a London server

Link between London and Singapore can sometimes get flooded with traffic

Printing some time very slow


They are asking for any changes need to made in Farm and any recommendation.

Can anyone help me on this.. I am also seeting all the details But any recommendation would great.


Note:- I am not understanding one part that "Round Robin with WI".
I know round robin iis use for what reason... But could any one help me on this area also appreciated.

Thanks

This is more than likely a timeout set for the Web interface, would require more detail on the error.

 Installing Citrix on new London Servers sometimes fails.

Again, what type of errors ?

If stopped sometimes IMA Service will not start on a London server

Have a look at this guide to troubleshoot:

Link between London and Singapore can sometimes get flooded with traffic
Use something like Wireshark (Freeware network sniffer) to see what is going on.
Also, 1 MBps is not alot of bandwidth, has the pipe been correctly sized for the
amount of Citrix users ?

Printing some time very slow
More than likely bandwidth issues here again.

More detail required on the farm setup.

It is more than likely that the WI's have been setup on servers that have WLBS installed on them. WLBS
enables a virtual ip to be load balanced across all servers in the cluster.
