Native boot quick,but same interface program,Jar mode is faster than native mode

    @GetMapping("/map")
    public Object map() {
        Map<String, Object> map = new HashMap<>();
        map.put("wgh1", 12);
        map.put("wgh2", "12");
        return map;
    }

This is in line with the expected performance of GraalVM native images. They generally start much faster and consume less memory but may have lower peak performance. Performance is an area of focus for the GraalVM team and it's improving with each release. You'll also see better performance with GraalVM enterprise edition as shown in this blog post.
