Transition Technology: Ticket #604: Times for admin tasks

ed — Tue, 15 Oct 2013 08:08:16 GMT

today it took more than 2 mins for this https://www.transitionnetwork.org/admin/content/node/overview

Ed, can you please note the date/time this happens so we can try to relate the slowness to munin and work I'd been doing (which might have emptied the caches and made it slow temporarily). Thanks!

hours, owner, totalhours, component, priority changed

chris — Wed, 02 Apr 2014 10:57:15 GMT

hours changed from 0.0 to 0.1
owner changed from jim to chris
totalhours changed from 0.0 to 0.1
component changed from Drupal modules & settings to Live server
priority changed from major to minor

Replying to ed:

It just took 13 seconds for me.

58 seconds: https://www.transitionnetwork.org/admin/user/user/create

That took 8 seconds.

I think this has been solved with ticket:593#comment:12 -- Ed can you confirm that this ticket can now be closed?

status changed; resolution set

status changed from new to closed
resolution set to invalid

trying it now was OK; it seems much slower in the mornings, and I hear from Rob and others at TN tht the first admin task of the day is very slow. But no more work of this nature on TNv2 so closing.

The caches will be cold first thing - so will always be slow as they're rebuilt by the early admin jobs.

It looks to me that BOA is set to kill the Redis cache at midnight -- I suspect this is the primary cause of this issue and would suggest that this theory could be tested by disabling the wiping of the cache.

OK, but please do bear in mind that this is probably a BOA "feature" -- this is the opposite of how Redis is supposed to be run:

Redis is designed to be a very long running process in your server.

It looks like this "feature" should be removed with the BOA upgrade on ticket:707:

is there a reason to restart redis every night?

Next BOA release will... be able to get rid of this reset procedure.
