If the initial start time is too slow even after rebooting or restarting IIS, you can edit settings to lower the startup time.
1. Stop the Workflow Service.
2. Open the Asi.Workflow.Service.config file.
3. Find the <SystemParams> section and add the following:
<!-- Url to the application server this is installed for. -->
<add key="ImisWebServerUrl" value="http://localhost/iMIS/"/>
<!-- Value given in minutes. Default value is 15. -->
<add key="PingInterval" value="15"/>
<!-- Comma-separated list. Example value: "http://server1/iMIS/,http:server2/imispublic/,..." -->
<add key="AdditionalUrls" value=""/>
4. Restart the Workflow Service.
Tip: There is also a "keep-alive" service for all CM-managed sites, to automatically pre-load sites in IIS if they are restarted, to improve the load time for the first browser request. You control this service through the PublishService.exe.config file (see Adjusting the website keep-alive service).
