Time Nick Message 23:32 cait hm' 23:14 talljoy good day #koha 23:14 talljoy dang it wrong channel again. lol 23:13 talljoy dani how goes round rock? 23:13 talljoy good day 22:18 rangi running 3.22 22:17 rangi https://obs.library.workbuffer.org/ 22:17 rangi i have a site running plack both staff and opac and there is nothing in /tmp 22:16 rangi (oh and sessions if you have sessions in tmp not mysql or memcache) 22:16 rangi but the fastmmap stuff is 22:16 rangi its not 22:15 tcohen it seems that some permission issues i've been sufffering running plack+3.22 in production are related to that 22:15 tcohen how is plack related to files in /tmp ? 22:15 tcohen rangi, i leave a question for you 22:15 tcohen HEA++ 22:15 tcohen :-d 22:15 tcohen yeah, that's why i put my libraries there 22:14 rangi (60% of hea that is) 22:14 rangi yeah about 60% have the pref off, so checking that before putting the link in the template (if we dont alredy) would save 60% of the libraries a bunch of time 22:13 rangi i suspect that most people run with localimages off 22:12 rangi cos doing that check in the template would be pretty easy eh? 22:12 rangi do we link to the image even if local images are turned off? 22:10 rangi can do both of course but then opac-search.pl itself would be slower 22:09 rangi then it wont slow the page down 22:08 rangi (you could make it fall back to static if people had js turned off too) 22:08 rangi its a static link right? not an ajax one? 22:08 rangi then it wont slow the page load down 22:08 tcohen it is 22:07 rangi or make the link be client side via js 22:07 rangi maybe 22:06 rangi hmm? 22:04 tcohen i bet checking local image existence in opac-search.pl and putting the URL on the template, would save at least a couple seconds to the end user 21:59 rangi yep 21:58 tcohen rangi: interesting that no local-images == high latency due to the check 21:41 rangi but yes it makes no sense to have plack hand out any static stuff 21:40 rangi hmm only the stuff that actually is :) 21:39 tcohen maybe we can teach apache/nginx some stuff are static content 21:33 rangi ill try it after work tonight 21:33 rangi then varnish should cache it 21:32 rangi (in the varnish config) 21:32 rangi } 21:32 rangi unset.req.http.cookie; 21:32 rangi if (req.http.Content-Type ~ "image") { 21:30 rangi something like 21:30 rangi altho, probably could ignore the cookie on images .. and even return them for logged in users 21:30 rangi (until they login that is) 21:29 rangi once one person has seen them, they are cached for everyone 21:29 rangi then thats a massive improvement 21:29 rangi and if you have something like varnish caching those images .. for a day or 2 21:28 rangi but if someone refreshes the page, thats 20 hits .. that will all be a little faster 21:28 rangi so if you are running cgi, its not going to be much faster for a single request 21:27 rangi it still hits the perl, so has to do overhead of loading modules etc (if cgi) but doesn't have to fetch the image from the db, and return it etc 21:26 rangi cool 21:26 tcohen i'm intrigued because I see a lot of time is spent on local images 21:25 tcohen it does 21:21 rangi make sense? 21:21 rangi so that if it 200s it sets a last modified, so the browser can ask for that 21:21 rangi -Last_Modified => strftime('%a, %d %b %Y %H:%M:%S GMT', gmtime), 21:20 rangi you have to make sure that it is setting a last modified too 21:19 rangi varnish will of course respect that too 21:19 rangi http://paste.koha-community.org/378 21:19 tcohen ah 21:19 rangi that code i pasted before 21:19 rangi nope 21:19 tcohen ? 21:19 tcohen rangi: so the 304 for opac-image.pl is varnish's responsability 21:18 * cait has a ginger ale 21:17 * tcohen joins bag 21:15 * tcohen feels like serving a chilled jaeger 21:07 * cait tries some old sample records from the original bug 21:06 rangi not recently 21:05 cait i have problems to get it show up 21:05 cait did someone try html5media by chance? 21:05 cait hm 21:04 * bag thinks it’s time for a martini ;) (I’ve got a brisket on the smoker since 7am (7 hours ago) ) should be ready in another 3~4 hours :) 21:02 bag yeah we spent sometime looking at varnish too 20:49 rangi i love curl 20:46 rangi [off] curl -I --header 'If-Modified-Since: Mon, 04 Apr 2016' https://library.charteredaccountantsanz.com/cgi-bin/koha/opac-image.pl\?biblionumber\=85364\&thumbnail\=1 20:46 rangi you can test with curl too 20:44 rangi they both behave a bit differently i found 20:44 rangi yep, what does firefox says 20:42 tcohen ah, status=200 but chrome says "From cache" 20:42 tcohen not here! 20:41 rangi opac-image.pl does the 304 thing there 20:40 rangi [off] https://library.charteredaccountantsanz.com/whatsnew/#/all/ try that, then do a refresh 20:40 tcohen rangi: i mean local cover images 20:40 rangi well im testing it with one client 20:40 rangi they do now 20:38 tcohen (and they don't) 20:38 tcohen cover images should support 304 20:38 jcamins rangi: yeah, 304 support would be a pretty big win. 20:37 tcohen i trust nginx caching capabilities, still 20:37 tcohen rangi: i'll be looking forward to your results 20:35 rangi otherwise you are right, it mostly helps with scaling 20:34 rangi jcamins: yeah the trick is when you start caching the .pl files output where you can that you start getting the speed benefits too 20:34 jcamins FWIW, I found that using nginx for static files was only about 10% slower than Varnish under relatively low load, but I believe when you start increasing the load to high you'd start seeing performance benefits. 20:34 rangi before it even runs the rest of the script 20:34 rangi and exit 20:34 rangi then hand them back a 304 (page not modified) 20:33 rangi if so, and its less that my timeout 20:33 rangi that says did the browser ask me for a last modified before 20:33 rangi before the script does anything else 20:33 pastebot "rangi" at 127.0.0.1 pasted "caching stuff" (10 lines) at http://paste.koha-community.org/378 20:32 rangi can do 20:32 rangi if you wanted to be really tricky 20:32 rangi then vagrant (and some browsers) would respect that, and not ask for the page again 20:31 rangi -expires => '+30m', 20:31 rangi print $data->header( 20:31 rangi if user not logged in 20:30 tcohen it does so matching the pages styles 20:30 rangi so for opac-main.pl if we did this 20:30 rangi but it still would be good to try 20:30 rangi yep, we are doing that with mod_gzip etc already 20:29 tcohen the good thing about pagespeed is that it shrinks images, and that kind of stuff, apart from the cche pthing 20:29 rangi 3.22.x is quite a bit faster with the caching work done, but if we are serving essentially static pages (like opac-main.pl before you login) we shouldn't even have to touch plack/apache if possible 20:29 tcohen hehe 20:25 rangi caching is like security, it's good in layers 20:24 cait hmmm 20:24 rangi trying out pagespeed would be good too, but its much less simple to understand :) 20:24 rangi or you can make it do more, it starts very conservative/safe which is a good default 20:23 rangi and it works by obeying the headers 20:23 rangi you can just put it there, and do nothing 20:23 wahanui interesting is sometimes good and sometimes bad 20:23 tcohen interesting 20:23 rangi yes 20:22 rangi varnish serves you the one from the cache, without bothering apache 20:22 rangi but it also means, if I hit it, then you hit it 20:22 tcohen so the main advantage is that varnish caches pages 20:22 rangi because browsers/proxies don't always behave how they should 20:22 rangi which means vagrant caches it 20:22 rangi we do 20:21 tcohen we should set the right headers for static stuff anyway 20:21 rangi (ie it wont cache stuff it shouldnt) 20:21 rangi and hence I actually trust it 20:21 rangi it's a lot less 'magic' than that google stuff 20:20 rangi basically vagrant respects the headers we put on stuff 20:20 tcohen https://developers.google.com/speed/pagespeed/module/ 20:20 rangi hmm? 20:19 rangi but it scales much higher 20:19 tcohen rangi: is there still that google module for caching? 20:19 rangi it's not a lot faster (it is faster but not a lot) than without vagrant 20:18 rangi you need nginx or something in front to do ssl termination 20:18 tcohen ah, idiomatic issue 20:18 rangi varnish serves them from ram 20:18 rangi it means theres a bunch less requests that hit apache 20:18 rangi nope 20:18 tcohen you mean it w¡got worse? 20:17 rangi it takes a lot of load off apache/plack 20:17 rangi and so is opac-main.pl if the user is not logged in 20:16 rangi all of the js/css/images are cachecd 20:16 tcohen statc content? 20:16 tcohen for caching stuff? 20:16 rangi in front of the opac 20:16 rangi i've been experimenting with varnish 20:16 tcohen hey rangi 20:15 rangi hi tcohen 20:15 tcohen hi cait 20:06 cait :) 20:06 wahanui hey, cait 20:06 cait hi 20:04 tcohen hi 20:01 cait morning bag and rangi 20:01 rangi morning 20:00 * cait waves 19:40 wahanui kia ora, bag 19:40 bag hola 17:50 huginn 04Bug http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=13438 normal, P5 - low, ---, m.de.rooy, Needs Signoff , Convert normarc framework plugins to new style (see also 10480) 17:50 magnuse marcelr++ for bug 13438 14:43 * cait waves
