Bug #2368: sendfile(2) freezes for a few seconds
Author: Francois Tigeot
Having updated a web server to apache-2.4 (sendfile enabled), I noticed
some static images didn't load in one go:
- top parts are displayed instantly
- image downloads freeze for a few seconds
- missing bottom parts are then downloaded and displayed instantly
Switching EnableSendfile between on/off in httpd.conf enables or disables
this behavior 100% of the time
