--------------
There appears to be a bug in the way the interval times are calculated. This problem doesn't explain why your scans are slow, but it may show you where the bottle neck really is.
The bug is in the deltatime function which calculates the time it takes to process each section of the code. the deltatime function creates a lexical $last_time variable in the scope of the function whereas it really should be using the global copy. The dependance on global variables throughout all the functions makes it very easy to make a scoping mistake like this.
This bug may explain why it looks like everything happens blazingly fast, except for the very last stage.
A trivial patch is included below.
