Test routines takes too long to start!

Hi,

   I'm using TestComplete 12 (12.50.4142.7 x64 more exactly) to test Java desktop applications over Delphi script language, and my project tests are taking about 2 or 3 minutes to definitely start. My computer is a Dell Latitude 3540 Core i7-4500U 1.80GHz, 8 GB RAM DDR4 with a SSD disk on Windows 10 Pro (quite as good for the system minimum requirements).

   My project today has more than 900 script routines (48677 lines) in a single test Unit, but at the beginning when it was about 100 script routines, the loading time was much less. I've read about how TestComplete load those tests and I saw there was a compiling procedure before the test run.

  I want to know if there's any way to improve my test performance by reducing this loading time. Beforehand, I can't split those tests into smaller test projects.
