In general, no. The performance of the API depends on both the
database and the 3 Rails application servers that handle all the
requests (i.e. converting db results into xml documents etc) and a few
other things too. Any number of things going wrong can make it go
slowly, and some of the graphs look similar under different scenarios
so if one chart showing a peak coincides with problems last time it
doesn't always follow that the same thing will happen again.
