Execution order of Scheduled reports

Hi

I was searching for this in the forum, but I didn't find any post related, sorry if it's already answered.

Question is the following:

We are preparing to enabling report distribution by email in PUC, linked to a Public Schedule. We'd like to check if there's any limitation in the number of reports that can be added to a given schedule.
Is there a risk to the server stability in case that let's say there are 100 reports added to the same schedule?
Will Pentaho try to execute all of them simulatenously, or one by one, or they will be executed in batches of 5, 10 or other predefined parameter?
Can that execution behaviour be controlled via parameters?

Thanks in advance

Jorge
