Re: On elisp running native

[Zhu Zihao]

I' ve read some code of your benchmark. And there's a simple way to optimize
these bench programs a littel bit.

For some program use cl-defstruct, you can put `(cl-declaim (optimize (speed
3)))` in the file. This instructment will tell Emacs byte-compiler to delete
runtime type check code (which is harmful in bench game) in struct accessor.

An example is
https://gitlab.com/koral/elisp-benchmarks/-/blob/master/benchmarks/nbody.el.

After adding instructment and byte-compilation, the bench result is

(benchmark-run (elb-nbody-entry))
;; => (28.996680579 107 15.392465563000002)

28s was taken in 1000000 times iteration. And I believe native-comp will get
better result.
