I got bored again, using my dev box,
Note, being a dev box, I can afford the luxury of rebooting before each
test to ensure no caching...
The VH segments we use in the real world are twice as big with suexec,
rewrites, php flags and Dir specific options, but this should give you
some sort of idea using a very, very, plain and bare bones config...
If the OP is that worried, he can use the script to do a dummy run using
all his real world config sections, which likely are two or three times
bigger than the bare test below...
Created 2000 files (see below)
time /etc/rc.d/rc.httpd start
real 0m7.490s
user 0m1.044s
sys 0m0.584s
ls -la /usr/local/apache/conf/vhosts/2000test.com.conf
-rw-r--r-- 1 root root 524 Feb 15
13:25 /usr/local/apache/conf/vhosts/2000test.com.conf
Slightly changed the "open" to send to all one conf file
time /etc/rc.d/rc.httpd start
real 0m5.623s
user 0m0.976s
sys 0m0.444s
ls -lah /usr/local/apache/conf/vhosts/hosts.conf
-rw-r--r-- 1 root root 1.6M Feb 15
13:19 /usr/local/apache/conf/vhosts/hosts.conf
Test script used -

$DOMAIN = $count ."test.com";
$htroot ="/var/www/vhosts/".$DOMAIN;
mkdir($htroot);
mkdir("$htroot/logs");
