If you have not too much data in the heap, you are safe. Even if you have a lot of data there, you most probably fine too.

As an example, see here: https://bazqux.com/ and the discussion is here: https://news.ycombinator.com/item?id=5961570

He was able to survive unexpected slashdot effect from being on the front page of Hacker news without even noticing it. He told me he went up one evening and found that there were tens of thousands of new users actively trying his site. So he added a couple of servers and went to sleep.

GHC development is very active.

And the answer to your last question is No.

Okay, but surviving a Slashdot effect is different from having a low-latency server of course :)

He didn't tell me that anyone complained about delays, etc.

I think delays weren't that noticeable then.
