First, you did "EnableSendfile off", right? Assuming so :) there is also the fact that mod_ssl will encrypt/pass 8K buckets at a time, while the core output filter tries to send the whole mmap()ed file, keeping what remains after EAGAIN for the next call (if any). That's I think a big difference too, especially on localhost or a fast/large bandwidth network. Regards, Yann.
