Indeed you have found the problem, I believe: Range headers. In order to handle out-of-order range requests (which are allowed by the spec), httpd must buffer the entire response. Of course, that is very bad behavior. Instead, httpd should just ignore out-of-order range requests (which the spec also allows) and serve the entire thing. And it shouldn't be necessary to do the buffering when the ranges are in order. I know this has been discussed on the dev list, but I can't remember the conclusion. There is probably some way to get httpd to ignore the range header, either using the RequestHeader directive or using one of the special environment variables. But I've never done it myself.
