Subject Re: httpd 2.4.25, mpm_event, ssl: segfaults
Date Thu, 16 Feb 2017 09:49:09 GMT
Here are some SSL/core_write outputs (sizes) for me, with 2.4.x.
This is with a GET for a 2MB file, on localhost...

Please note that "EnableMMap on" avoids EnableSendfile (i.e.
"EnableMMap on" => "EnableSendfile off"), which is relevant only in
the http (non-ssl) case anyway.

Outputs (and the patch to produce them) attached.

TL;DR:
- http  +  EnableMMap                    => single write
- http  + !EnableMMap +  EnableSendfile  => single write
- http  + !EnableMMap + !EnableSendfile  => 125KB writes
- https +  EnableMMap                    => 16KB writes
- https + !EnableMMap                    => 8KB writes
