Hi,

A question related to Appian Performance, we are trying to analyzing how web service call load impacting our performance in production, one thing we have noticed is for shared process model which includes the web service call node, the duration of the process execution for UI chained is much faster than it was called by the back-end parent process model, which means not in the activity chain, is it what Appian behaves normally? UI chained process model call takes priority?

If anyone could help clarify this, that would be quite helpful.

Thanks,
Ping

Appian works using both foreground and background operations.
When activity chaining is enabled, the nodes are executed in the foreground, take precedence, whereas unattended nodes that are not chained are executed in the background. When a node is executed in the foreground, it will execute with a higher priority over the nodes executed in the background, thus completing faster. Attended nodes, chained or not, are always executed in the foreground.

However this should not be used as a solution to execute nodes faster. We need to find out where the bottleneck is and make the process run fast without unwanted activity chaining.
