Out here we are touting a 4sec as the maximum.

when people started doing timesharing in the early 60s, there were several
studies of this. The result was that if the response time is more than 2
seconds
productivity begins to hurt. But more important than the raw response time
was that the response time was constant, thus response times of 1, 1, 5, 1,
1, 4, 1, 1, 1, 1 with a mean of 1.7 seconds was worse than 2, 2, 2, 2, 2, 2,
2, 2, 2, 2 with a mean of 2.0 seconds, although the latter was slower on
average. A consistent response time that does not vary much is best.
