The best strategy for discovering causes of slow execution and eliminating the problem is a mixture of problem reduction and the techniques below. The problem reduction strategy will not be discussed here (see the Small to Large chapter). Beyond that the strategies one can used involve
| • | Tracking program execution through screen watching and LOG file / process window contents examination. |
| • | Tracking program execution characteristics through profile and profiletol usage. |
| • | Finding problems within large slow statements by searching and code isolation. |
| • | Finding problems when GAMS goes on forever and you cannot wait for the profile by searching and code isolation. |
