Initial page load too slow

[sedubois]

There's something quite inefficient going on e.g in the with-apollo example, the initial page load is way too slow:

PageSpeed Insights confirms (score of 75/100), sometimes saying the server responded in 2.5 seconds, sometimes in 1.1 seconds.

As for Nextgram, PSI gives 100/100, but I still get a 5 seconds load time when trying myself:

BTW why doesn't Nextgram have the same chunks commons.js, main.js, etc?

Their could be ways to improve the perf using apollo, if you have multiple queries going at the same time, e.g. using batching-interface and deduplication.
Don't know if it would do anything in this example but in more complex projects maybe..

[sedubois]

@alikhani There's a single query in this example, so it doesn't explain the current issue.

[sedubois]

@marktani suggested to check Pingdom, similar results (tested from NYC):

• With-apollo (code, pingdom):

• Nextgram (code, pingdom):

• Next-news (code, pingdom):

[marktani]

Interesting interaction: after you loaded the page and reload it, Chrome DevTools show between 2 and 4 seconds needed to "Request ServiceWorker".

[sedubois]

@arunoda would you have an idea about @marktani's observation regarding service workers?

@marktani @sedubois #957 and #1004 might be related

[arunoda]

@sedubois This might be related to now.sh's container start time or something related.
I've also seen that.

But for the 2nd page reload (after deleting the cache) it works pretty well

[sedubois]

@arunoda even after several page loads, the 1.7 seconds wait time was still present. So it's not just container boot time.

[sedubois]

The screenshots above were made when Now containers were already booted.

I added Next-news (which was just updated to latest Next.js by @rauchg) to the list of Pingdom screenshots above. But also 2.9 seconds waiting time.

[sedubois]

This would be something with the whole now.sh infrastructure? Because now all response times are twice smaller (pingdom test from NYC: 982 ms for with-apollo, 1.39 sec for nextgram, 1.22 sec for next-news).

And earlier today my own app (https://relate.now.sh) had sometimes a 25 sec server waiting time, and now it's down to 783 ms.

Maybe this issue should be opened on Now's side.
