As for the number of booms per day, the booms only occur at very specific times of the day (which coincide with various jobs that we run which calculate features for the forum and elsewhere, as well as to clean up the forum's indexes to keep it fast). So if you visit and get 5 booms, that doesn't mean others will be getting booms throughout the rest of the day. It just means that you happened to visit while there was a lot of server load (on our end, not by the number of visitors) and got a boom as a result.
Keep in mind that we also try to run the jobs separate from each other and at times where we have the lowest amount of traffic. Due to the number of jobs, however, we end up having some long-running jobs lasting into the afternoon. We are still trying to find out the best schedule for these jobs, and we will continue experimenting until we find a good setup.
