Default parallelism?

[ngregoire]

Hello,

in the extension's config, I see a way to configure a delay between requests (which defaults to 1s) but nothing related to parallelism (i.e number of threads). For a complex scenario where Preflight + ReDownload + macros are needed, I need to have no parallelism, aka use a single thread.

What is the default number of threads? And if it's not mono-threaded by default, hwo can I configure the extension to behave this way? Thanks in advance!
