  Re: Optimize cold load time by concatinating common JS files   
 

  
 
 
 
 

 
 There was some work I was doing on bundling some time ago (that we parked) around making them "more accurate" in terms of what should be in them. I know that sounds vague (and I can explain more if you don't find it too boring - bundling is not all that exciting), but the upshot in terms of bundle sizes is expected to be varied in that some bundles will get slimmer (removal of modules that should not be in there) and some may get a bit heavier (addition of some modules that should be in there). All post 1.0 as it's not biting us atm.

 We have tried it before (see below). I suppose I'm just not too gone on fundamental build changes for what really seems to be an edge edge case. How many production setups run Jenkins on one side of the world and expect cold loading to be fast on a browser on the other side of the world?

 It is possible. We had it that way before and moved to splitting it out to see if async loading would help and it did seem to at the time.

 Yoann Dubreuil if we could try it on some server, it would be worth it as cold is exactly the case we want ot optimise for right now.

 I rolled back my changes. Anyway, given it was only useful for cold caches, it was not worth it.

as optimized as possible OOTB before looking at these higher level things
 Imo, we are at that point after we do the likes of JENKINS-40941 i.e. not what's being proposed/requested here.

 Configuration done. But it will not really be helpful, most things are already cached by the browser anyway. Could help a bit for cold cache maybe.

 Could we hold off on any changes that might require users to setup their http proxy in a very specific way? We need to ensure this is as optimized as possible OOTB before looking at these higher level things

 I can enable caching for all BlueOcean static resources on the reverse proxy side, I think it could be interesting to see the effect. What is killing performances is latency and avoiding Jetty should be helpful. I'll configure this in sandbox.

 legal in california.  But more seriously, chrome will only load 6 at once, so all 3 of these take on one loading "cascade". All we can do is experiment and iterate (now we can measure, thanks to PR builder).

  Re: Optimize cold load time by concatinating common JS files   
 

  
 
 
 
 

 
 From the "arse end of the world" a cold load is now about 12s, which seems a reasonable reduction. Collapsing those js files would get it to probably 10s, not huge, but something. So yeah, everything helps a bit. I think http2 is out of reach of a lot of people still, but it is good to know it makes a good difference.  In terms of metrics: https://gtmetrix.com/reports/ci.blueocean.io/RUoAc9Hh is a bit better. Aiming for 1s by that measure so this is close... Other than that, there are likely other opportunities to speed up the "subjective" experience (time to showing something on screen, what was there previously.. but for another ticket).

 I reworked the HTTPS support for the sandbox, and I took the opportunity to add support for HTTP2 on it. This and TCP Fast open leads to a much less latency. I applied the work to dogfood too.

 I'd be more inclined to leave this particular one until after we eliminate as many other requests as we can. All others would be lower hanging fruit.

 Tom FENNELLY   the gtfx score isn't so bad compared to many websites, where things fall apart seems to mostly be to do with latency, not so much size of artifacts.  Once you introduce latency a bit, things slow down exponentially.  not sure is that helps with sleuthing things down...

 Yep  NPM package usage explosion. I had been doing work on slimming down the generated bundle packages at one point. We parked it though, as other stuff was deemed more important. Some of that "might" help a bit, but bottom line is ... we have quite a few npm deps and some of them are quite hefty.

 Tom FENNELLY blueocean.js is already 700k - I think all those files would increase to >800k (700k is too large anyway). Worth exploring what the options are here if possible before committing to it.

 This is not as easy as it might sound "in theory". Easiest way might be to bundle them directly in {{blueocean.js}} , which is what we used to do but then split them out because that was seen as a performance bottleneck .  I feel like we get caught one way or another on these things  we should try use fewer packages.

 Just like JENKINS-40932 we want to combine some files together to improve the browsers parallelise requests (we do too many requests - see the [Waterfall|https://gtmetrix.com/reports/ci.blueocean.io/kV6QiMBy] report).These JS files should be concatinated into a single resource and served to the browser together: * react-router* react-redux* reselect* keymirror* redux-thunk* immutable This awesome tool provides some insight into what can be optimised (page speed + yslow + waterfall): https://gtmetrix.com/reports/ci.blueocean.io/ijzy6djdYou can see from this, having fewer http requests wil allow the browser to do less "waterfall loading". Once we have this, we can revaluate on hi and low latency connections (low latency things are much worse than that tool shows, about 10x slower for cold load).

 Just like JENKINS-40932 we want to combine some files together to improve the browsers parallelise requests (we do too many requests - see the Waterfall report). These JS files should be concatinated into a single resource and served to the browser together:  
 
react-router 
react-redux 
reselect 
keymirror 
redux-thunk 
immutable
