@Yadigar can you clarify your question. Is the context of your question more about the performance difference between a scheduled workflow or an event-based workflow?

I'm actually wondering regards the performance difference between creating WF for individual transaction type or WF for several transaction types? for example WF for email notifications

Depends on what context you're working on. For example if it's a scheduled workflow and you're working on all transaction types, it will take longer since you're processing all transaction types.

@Lea CC Thanks for your comment. Regards UI context, does it actually matters?

You mean event-based?

Yeah

No. I don't think it matters.
