One example would be a high amount of throughput. We often see it during busy seasons like Black Friday and Christmas for the retail industry or for insurances a few days before its the deadline to get an insurance for the next year. Often, systems cannot handle the insane load of e.g. 10x more requests.
Other causes for a high response time can also be timeouts, where there is a wait time before a timeout/no response is returned. E.g. calls to an external service of a partner company for which the website is down.
I also often see response time degradations for large document sizes (can very even for the same request, imagine for example that someone uploads a picture this will always have a different size per customer who uploads) or also faulty/lengthy database statements.
