CFNetwork flash during image retrieval

Question

I profile my application in Tools and have discovered an alarming amount of CFNetwork distributions when I use AFNetworking to retrieve a remote image.

In one instance, I saw 89 MB of distributions (image size is only about 200 KB). I added a screenshot to demonstrate. Has anyone else noticed this before? The memory is released accordingly, but I cannot understand why this is happening in the first place.

Thanks in advance.

I see the same problem on iOS 8 ONLY. This does not happen on any version of iOS 7. On its simulator 132kb, on its device 144kb.
