If the delay is at the reading side, away from Akami, through a cache, perhaps 10 concurrent requests for X would result in ten lots of data transfer as it isn't in cache yet, but 10 with a short delay is enough to prime the local cache on the first request before the rest start.
There are a number of reasons a sudden glut of activity could balloon bandwidth or CPU/memory costs more than you might expect.
Without a chunk more detail about the system in question, this is just random speculation of course.
- mlyle 4y agoGood points. Thinking about this-- this is Akamai, who has historically charged for midgress. Liveness of cache could be very important.
