Many more things dynamically update than before, and do so more often.
Opening up 5 dashboard instances basically turns the box into a
relatively busy web server, doing probably a few dozen requests per
second depending on which all widgets are enabled. Yes that will chew
some CPU on an old Atom.

[pfSense] CPU Utilization on landing page

2016-06-23 Thread Karl Fife 
Ever since upgrading to 2.3, I notice that the CPU utilization is 
uncommonly high when a browser is pointed at the Status / Dashboard.


Naturally, this is the php-fpm process.  Each instance of php-fpm runs 
at between 8 and 40% of my 1.8ghz Atom (dual core, HT).  With four or 
five dasbord windows open and I can burn 70% of the CPU on the idle 
box.   Doing the same on <= 2.2 barely registers additional utilization.


Disabling active widgets (traffic graphs, firwall logs) reduces the 
utilization slightly, but it's nowhere near what it was <= 2.2.


Is something wrong here, or is this new framework simply more resource 
intensive?  Certainly I'd expect the client to be working harder with 
the javascripty bootstrappy interface, but I would not expect a pfSense 
workload change.  In our case, all of the upgraded instances (4) behave 
the same, and all are running on the same Lanner FW-7541D, so maybe 
there's an idiosyncratic problem with that hardware.


Is anyone else seeing this?
