Are there any disadvantages if we change the process execution property CHAINED_EXECUTION_NODE_LIMIT from the default 50 to 200? FYI. the server is a cloud.
Thanks in advance. ...

When many nodes have to be executed (let's say Script Tasks), the user doesn't know that this is happening on the background and it might give the impression that there is a performance/lag issue which, is not necessarily true. Keeping a low number of nodes prevents this from happening.

While the impression of lag is a bad user experience, a broken chain in a wizard is a far worse user experience (they need special training to know to look for the next task in their task list). Aim to decrease the node count on the chain as much as possible, as surpassing the limit indicates that the design should be improved. But sometimes a high number of unattended nodes in unavoidable, and I personally found that it is better to increase this limit than allow the chain to be broken.

Also note that there is a hard limit of 100 nodes (I think), so increasing to 200 will not have any additional effect.

Alok, can you verify if the 100 hard limit is indeed the case? We are at 100 currently, have considered going a bit higher - would be good to know if that is not possible.

The hard limit for this is indeed 100.

Also we must not forget that there is a limitation of 8 seconds also. So chaining will break whichever condition reaches first.
