/fast

Syntax:

/fast

The /fast option sets several options that generate optimized code for fast run-time performance. Specifying this option is equivalent to specifying:

• /alignment:(dcommons, records, sequence)
• /architecture:host
• /assume:noaccuracy_sensitive
• /math_library:fast
• /tune:host

If any of the /stand options are also specified, /align:dcommons and /align:sequence are not set.

In the visual development environment, specify the Generate Most Optimized Code in the Code Generation Compiler Option Category.

If you omit /fast, these performance-related options will not be set.
