[New-bugs-announce] [issue43760] The DISPATCH() macro is not as efficient as it could be.

[Mark Shannon]

New submission from Mark Shannon <mark at hotpy.org>:

The DISPATCH() macro has two failings.

1. Its check for tracing involves too much pointer chaser.

2. The logic assumes that computed-gotos is the "fast path" which makes switch dispatch, and therefore Python on Windows unnecessarily slow.
