本地跑的,cpu是i9-13代,内存32G
方法是这个:
代码语言:javascript复制public static void main(String[] args) {
int i = 1000000;
int i2 = 100;
StopWatch watch = new StopWatch();
watch.start();
Set<Long> ids = new HashSet<>();
for (int i21 = i2; i21 > 0; i21--) {
for (int i1 = 0; i1 < i; i1 ) {
ids.add(IdUtil.getSnowflake().nextId());
}
System.out.println(ids.size());
}
watch.stop();
System.out.println(watch.getLastTaskTimeMillis());
}
实际跑了7600万,然后OOM了,内存是8G
