Quite likely.

As a test, I just run, in an actual TI-59, the diagnostic program directly from the Master Library:

Code:

  Pgm 01 
  SBR =

It took 14.8 seconds.

Then I run the same program from memory:

Code:

  Pgm 01
  Op 09     # Loads current module program into memory
  RST       # Deselects module program
  SBR =

It took 16.7 seconds.

Not a huge difference. Even taking into account the fact that the diagnostic program uses, in part, subroutines from other module programs, I would expect the speedup (running from module vs running from memory) to be closer to 50% than 200%.
