前端性能优化 - 如何解决前端图片加载时stalled阻塞时间过长问题（不是6个并发数限制的原因）？

Question

前端图片加载时stalled阻塞时间过长，而且从数量上看并不是由6个并发数的限制引起的，有两秒左右的时间所有请求单纯的阻塞着，没有数据传输

期望正常加载

点下面这里，就可以看到这些字段的说明。

见 网络功能参考 中的描述。

也可以参考英文原版：

Queueing. The browser queues requests before connection start and when:
There are higher priority requests.
There are already six TCP connections open for this origin, which is the limit. Applies to HTTP/1.0 and HTTP/1.1 only.
The browser is briefly allocating space in the disk cache.

Stalled. The request could be stalled after connection start for any of the reasons described in Queueing.

可能的原因就这 3 个。
