However, if you decide that the client-side extension should run across a slow link, regardless of the amount of data, you can enable these policies. It is recommended that you do not change these. Each policy includes a maximum of three options. Allow processing across a slow network connection. When a client-side extension registers itself with the operating system, it sets values in the registry, specifying whether it should be called when policy is applied across a slow link.
Some extensions move large amounts of data, so processing across a slow link can hurt performance.
Installing a large application across a 28.8 Kbps modem line is impractical. Do not apply during periodic background processing. Computer policy is applied at startup, as well as periodically in the background, approximately every 90 minutes. User policy is applied at user logon, then every 90 minutes. Some extensions process policy only initially, not periodically, because processing that took place in the midst of a user's session would be disruptive.
