Andy,
There is one more thing you could do is have the template precompiled in
a cache
Here is how you can set it up
cat <<EOF > /usr/local/pf/html/captive-portal/captiveportal.conf
name captiveportal
<View::HTML>
COMPILE_DIR /usr/local/pf/var/captiveportal/cached_templates
</View::HTML>
EOF
Then restart the captive portal
/usr/local/pf/bin/pfcmd service httpd.portal restart

Okay great. Thanks for the reply. I have done the following.
I have changed the following line to track the 'serving' time for a page.
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
\"%{User-Agent}i\" **%T/%D**" combined (added %T/%D)
For number of processes for httpd:
With a single device, after the pfdhcplistener is done, for the first
ever request to the captive portal, I saw 10 httpd processes. But for
all the subsequent requests, the number of processes were between 3-4.
This was for a single device on the VLAN.
I also couldn't find the 'worker' module configuration anywhere. So I
think httpd is running with default configuration as far as threads,
processes, connections etc.
I think, I should be adding the following sample configuration
somewhere, can you tell me here would this go?
ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
I have turned on the slow query log in mysql and no queries have
showed up so far, been running for past 3 hours.
Anything else that I can look at?

Hello
What's the best way to speed-up the serving of captive portal
pages to reduce latency?
Currently the latency of each page is quite high in 7-8 seconds
bracket.
Hi Andy,
Before anything you really need to know where the bottleneck is.
E.g. Improvements to the webserver (for instance) will not help if the
database is at fault.
Try to see if the httpd is hitting the maximum number of processes it
can handle concurrently for a start.
You may be swamped by what we colloquially call “parked devices”, i.e.
devices that constantly query the portal even though no one is
actually going to register (mostly phones).
Or you may have a single device that is trying to open hundreds of
connections to the portal.
If that’s not the case, try to see how long it takes to serve each query.
Apache can log the time per requests.
Enable the slow query log in mysql.
Etc.
Your question unfortunately does not lend itself to a simple answer.
Each server is unhappy in it’s own way.
Regards,
