Thanks. Will PF automatically pre-compile the cache if I add the following to
captiveportal.conf?<View::HTML>COMPILE_DIR
/usr/local/pf/var/captiveportal/cached_templates</View::HTML>
I currently have the default configuration for captiveportal.conf
# rename this file to captiveportal.yml and put a ':' after 'name' if# you want
to use YAML like in old versions of Catalystname captiveportal<Hooks> <Root>
<maxRegNodesReached> override Status index
</maxRegNodesReached> </Root></Hooks>

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.
