Hundreds of milliseconds can be "not a big deal" depending on what your program is, how often it's run, etc. The last time I used CGI was for the "sign up to my newsletter" on my website; the endpoint for that would lock a file, append the email from the form, and close it. Even if that takes a second (which it didn't, more like 50ms) then ... that would actually be fine for this particular use case of a small newsletter. Of course for many other things it would be horrible. I think "not necessarily terrible" is a reasonable way to phrase things.
