Recommended settings for high latency / low bandwidth client?

[akelly]

Using Wildfire 4 and Pro/Intralink 9.1

Have 2 off-site users that have low bandwidth / high latency connections
to our WAN. Was using portable workspaces to exchange Pro/Engineer
models, but are trying to find a solution to reduce the amount of data
being sent back and forth. They have registered our Pro/Intralink
server, but the upload / download speed from the Pro/Engineer client
seems to be a lot slower than the Portable Workspace method. Seems
counter-intuitive since Pro/Engineer client uploads / downloads
typically involve 1 or 2 models, but when you use a Portable Workspace,
it includes every CAD Document in the workspace.

I know that there are several TPIs regarding Pro/Engineer client
settings for Windchill integration, but does anyone have recommendations
that work well for low bandwidth / high latency clients?

We aregoing to test the ZERO CLIENTS. This is an improvement from the HP and Dell thin clients terminals. The thin client terminals from Dell and HP physically connects to a singe physical local server/workstation. The thin clients terminals are 1:1 ratio between terminals and local servers/workstations. Since ProE only uses 1 CPU core,it is a waste if you have multiple cores per CPU socket in your server. With Zero Client technology, we are going to attempt to connect to VM Desktops, thus efficiently utilizing the server with multiple cores.

There are some companies that currently offer it:

• http://www.displaylink.com/zero_client/index.php


• http://www.wyse.com/solutions/education/shared-desktops/multipoint/


• http://www.fujitsu.com/fts/products/computing/pc/zero-clients/bundles/


• http://searchvirtualdesktop.techtarget.com/definition/zero-client

We have offices in India and UK which are having latency issues and the data has to be secure in our systems and cannot be exported out. For ProE licenses we also have license server locally placed, borrowed or on their mobile system when users travel. For permenant remote users, we usually place a local license server at that remote office.

Andrew,
You should look at the following OS and config.pro settings to improve performance during upload/download.

Creo

1. Implement the settings in the attached config.pro file. Once this is done the user will need to unregister the Windchill server and reregister the Windchill server. This will allow the dm_http_compression_level setting to be recognized. You may want to increase the dm_http_compression_level to see if it helps. I think the max level is 9.

compress_output_files yes
dir_cache_max 500
disable_search_path_check yes
dm_cache_limit 0
dm_cache_mode none
dm_http_compression_level 3
dm_network_request_size 1000000
dm_network_threads 4
dm_synchronize_in_background yes

Windows (Not version specific)

1. Set the system page file using the following formula: (RAM * 2) + 640 MB.

Internet Explorer

1. Modify the registry to increase the http thread count to 10.

the great number one pro with Zero Client and Thin Client terminalsare that even if you have a complete cut of connection, you data and session in the server room is still running and you will not lose work. You completely remove the need and the equation of file or cache compression, because there is no file transfer.
