It is difficult to discuss this with so little
specific evidence.
The kind of evidence needed includes
1. What kind of program? Ideally Jitian might
be willing to make the program and dataset
available, or equivalent, available to others.
2. How far these timings really were obtained
under exactly similar circumstances. For
example, whether the program was in
memory first can be important.
3. Whether the observation really is repeatable
across both similar and different programs.
Finally, it is a broad principle that even
general speed-ups don't automatically mean
that absolutely everything is faster on
all possible machines in all possible circumstances.
The best way for Jitian to push this forward
is to liaise with Stata tech-support, who
would undoubtedly want to know much more than this.
