Force delay on apache response times

apache-2.2apache-2.4

Is there a way to make an Apache response time to take at least 10 seconds?
It's fine if it takes more than 10 seconds but I would like the fastest response times to take at least 10 seconds.

You can do this with mod_lua in Apache v2.4 and possibly mod_python/mod_perl with Apache v2.2 or v2.4.

You register a handler than simply waits 10 seconds and then returns apache2.DECLINED to indicate it will not handle the request, which should then process normally.

There is an example handler in the mod_lua documentation: https://httpd.apache.org/docs/trunk/mod/mod_lua.html

Apache – Why Localhost Response is Slow

For me, setting the ServerName property in httpd.conf fixed the delays (they were up to 10 seconds at worst):

# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
ServerName 127.0.0.1:80

Ssl – Apache – extremely slow initial handshake (SSL enabled)

This is with some Linux distro, right?

Is this server mostly idle? Perhaps Apache is shoveling randomness from /dev/random. That can be sometimes very slow, since /dev/random requires "real" randomness; stuff like moving the mouse, using the keyboard and network traffic gather the entropy. If the kernel entropy pool is nearly empty, processes requiring randomness tend to stall for a (long) while.

Should this be the situation, cat /proc/sys/kernel/random/entropy_avail should be near zero during SSL handshake.

You may switch the randomness source to /dev/urandom by using SSLRandomSeedApache directive, but be warned, this is theoretically not as secure as /dev/random.

Other solution is to use daemon like rngd (available from rng-tools package in many Linux distros) which fills up entropy pool.
