jstrebel:
Hi,
may be this interesting for you.
Installed 15.7
upgraded via seral console to 15.7.2
(followed the instruction of Franco about disable and enable the RAM disk)

I have not made any performance test. The fist impression is that the reaction of the OPNsense screens seem to be slow.
Load average after 2 hours and playing with the WEBinterface
load average: 0.65, 0.71, 0.66

Hi Jakob,

thanks for this. 256 looks like a doable amount. We've had trouble with 128 MB installations and OOM kills, but with 77 MB free this looks like a stable setup. Does the sluggishness also affect networking or only GUI responsiveness? It could well be the CPU not being powerful enough to run the PHP code.

Cheers,
Franco

PS: I still fear that fetching updates may fail sooner or later. There is no easy way out of this without RAM or providing a larger NanoBSD image (the current one is 1GB, but maybe it should be 2GB per slice).

Franco,
if I run top on the serial console and do some changes on the GUI I see that python is creating workload.
I feel it is important to keep a eye on, how opnsense is running on ALIX. Do you have some hints how I could find possible resources "hogs"
Jakob

franco:
Python wraps around the low level scripts as an intermediary for PHP. Sometimes it executes unix commands, sometimes shell script, sometimes even PHP scripts. It's a bit tricky to track a Python subprocess as the language does not have an optimal threading model.

One could e.g. measure script runtime vs. Python overhead by doing:

# /usr/bin/time -h configctl service reload all

vs.

# /usr/bin/time -h /usr/local/etc/rc.reload_all

Franco:
This is on ALIX:
0.31s real 0.24s user 0.06s sys
root@OPNs-tst:~ # /usr/bin//time -h configctl service reload all

1m6.07s real 0.22s user 0.07s sys
root@OPNs-tst:~ # /usr/bin//time -h /usr/local/etc/rc.reload_all
1m9.11s real 7.77s user 4.87s sys

And this is on APU:
root@OPNsense:~ # /usr/bin/time -h configctl service reload all

1m41.24s real 0.08s user 0.02s sys
root@OPNsense:~ # /usr/bin/time -h /usr/local/etc/rc.reload_all
