I assume "10mytes" is 10 megabytes? But it really doesn't matter since libcurl
has no buffers at all that fit even close to 5MB.

And you didn't mention what libcurl version on what OS so we can't make any
clever guesses based on that either.

Thus, I would claim the problem is in your network or in the server end.
