In order to take some work of the webserver I recently installed a lighttpd server for delivery of static files.
The following tuning did the job (thanks to the video sharing script)
/etc/lighttpd/lighttpd.conf
server.max-keep-alive-requests = 4 server.max-keep-alive-idle = 4 server.event-handler = "linux-sysepoll" server.network-backend = "linux-sendfile" server.max-fds = 8192 server.stat-cache-engine = "fam"
/etc/sysctl.conf
# These ensure that TIME_WAIT ports either get reused or closed fast. net.ipv4.tcp_fin_timeout = 1 net.ipv4.tcp_tw_recycle = 1 # TCP memory net.core.rmem_max = 16777216 net.core.rmem_default = 16777216 net.core.netdev_max_backlog = 262144 net.core.somaxconn = 262144 net.ipv4.tcp_syncookies = 1 net.ipv4.tcp_max_orphans = 262144 net.ipv4.tcp_max_syn_backlog = 262144 net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_syn_retries = 2 # For Large File Hosting Servers net.core.wmem_max = 1048576 net.ipv4.tcp_wmem = 4096 87380 524288
in the apache virtual host we just use proxy pass to forward our static urls to the lighttpd server running on port 8080
