Hi Florin,

Using the reference [1], you can view a dump of downloading the same file from the same linux server using the mtcp host stack ( buffer size has been set to 8192 bytes) . As you can see from the dump, there is no one buffer overflow. And in this case, even using an 8k buffer, we get good bandwidth. Thanks.
