Digi hasn’t released any benchmarks for the products. Customers are welcome to port existing benchmarks to Dynamic C to compare to other platforms.
Note that Dynamic C 9 is far from ANSI C compliant, and benchmark code may require significant changes to compile (for example, it doesn’t support initializers in variable declarations). Dynamic C 10 included many compiler and Standard C Library changes to better support ANSI C code, and may be a better starting point for porting benchmarks.
