If the settings cannot be balanced to avoid overloading the agent’s PC while still being able to send requests to the agent fast enough, then one of the following actions should be taken:
Consider reducing the polling rate configured in the Users section of the SSO Authentication dialog by increasing the poll time. This reduces the load on the agent, at the cost of detecting logouts less quickly.
In an environment with shared PCs, it is probably best to keep the poll interval as short as possible to avoid problems that could result from not detecting logouts when different users use the same PC, such as the initial traffic from the second user of a PC possibly being logged as sent by the previous user.
