assign_interfaces.php issues with large numbers of interfaces
On a firewall running 2.3.1, after creating ~200 vlans, assign_interfaces.php gets very slow while taking 100% cpu. when selecting "assign interfaces" in the cli/console, a lot of "broken pipe" errors turn up before the usual config dialog begins.
I can help with debugging, the box in question however is in production.

We have been doing some testing on one of our sites.
Under 2.2.4 no issue with 100 vlans, under 2.3.1-RELEASE-p5 at 40 vlans it takes around 27 seconds to open the page on our boxes and it is noticibly slower as you add vlans one by one.
At 100 vlans we get a 504 Gateway time out.
nginx: 2016/06/23 12:08:23 [error] 17180#0: *134 upstream timed out (60: Operation timed out) while reading response header from upstream, client: X.X.X.X, server: , request: "GET /interfaces_assign.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm.socket", host: "X.X.X.X", referrer: "https://X.X.X.X/".
This also happens under the i386 architecture.
Think this is the same as Bug #6520

Maybe this is somehow related to https://redmine.pfsense.org/issues/6515
When submitting a change in interfaces_assign, interface_configure() is called, and that calls link_interface_to_vips() - the performance of which is improved by the change for 6515, in commit https://github.com/pfsense/pfsense/commit/d75c55fbe2f98dfe782dfc9dc22f76765e4ef3c2
It seems to me it would only help in a situation where there are a number of VIPs on the system, as well as a bunch of interfaces. So I am not sure that it is related, but would be worth applying the changes in that commit and see if anything improves.

- File 1000-interface-config.xml 1000-interface-config.xml added
- Subject changed from assign_interfaces throws "broken pipe" errors to assign_interfaces.php issues with large numbers of interfaces
- Status changed from New to Confirmed
- Target version changed from 2.3.2 to 2.4.0
- Affected Version changed from 2.3 to 2.3.x
- Affected Architecture All added
- Affected Architecture deleted (
Not seeing any issues with 200 assigned interfaces (somewhat slower than 2.2.x, but still usable), but take it up to 1000 and assign_interfaces.php is non-functional. 504 timeout
example config attached.
2.3.2 is too near-term for significant changes, historically things along these lines have lead to regressions for the 99.99999% in interest of fixing the 0.00001%, so pushing this to 2.4.0.
