I downloaded the beta.

The documentation for the following command-line switch is not encouraging:

/optimize n
Set level of optimization from 0 (very very bad) to 10 (very very slow).

Should I choose very-very-bad or very-very-slow or something between?

Anyhow, I just tested the drop-in replacement switch for MSVC:

/vc Microsoft Visual C compatibility. The rest of the command line options are
as described by the Visual C documentation.

Microsoft:

cl /Ox /c chess_stuff.c
link chess_stuff
timing_test
20.9 seconds

Vector:

vectorc /vc /Ox /c chess_stuff.c
link chess_stuff
timing_test
29.3 seconds
