Running mod_ssl-only Apache (no external party modules), which is in
front (reverse proxy) of a non-ssl Apache.
With mod-http2 the memory footprint varies greatly:
Without mod_http2 a steady ~40 MB.
With mod_http2 it starts with ~50MB and peaks to over ~300 MB with a
average of ~130 MB and slowly growing.
Measured with 2 minutes interval, so the peak could be much higher.
Attached the graph from today.
The dark line is the non-ssl Apache.
The dip is the switch from 2.4.18-dev-http2-Alpha to 2.4.18-vote.
Happens with 2.4.17 as well as 2.4.18.
