Checkout Speed - Slow

9 0 1

Hi All,

Not sure if anyone can assist? We are getting a lot of reports from our customers that when they go onto the checkout page it's really slow and doesn't load. 

The rest of the website is fine (I assume the checkout page is based on a different server).

Does the different plans speed up the checkout pages?

Thank you for everyone who is participating here.
I have not even received a response from support for 6 days.

  • This is after I submitted everything requested.
  • Screenshots
  • Videos (from us and other shops).
  •  .har files (developer console records) both for when the checkout is working and when the checkout is delayed so they can compare

The only thing I get to hear is "it's not a shopify problem". When I refer to the thread here it's "we can't compare you to other shops".

Really a joke! Instead of addressing the problem, they try to sweep it under the table. Either they say "it's your theme" or "it's the apps" but they never accept that it's an infrastructure problem.

Please all contact support and refer to this thread. We need to increase the pressure to finally be taken seriously.

For all those who also want to send a .har file, here are the instructions

I also did speedtests on ,in the waterfall you can see that most of it is Shopify resources blocking the rendering.

I've also wondered this week if something isn't going on with checkout. I'm getting a lot of add to carts that go no further. Which is fairly unusual.

I believe we're still losing sales to this issue. I was able to reproduce it again and it took about 15-20 seconds to load the checkout page. The bug seems intermittent, I'm wondering if it has to do with cache eviction when changes are made to the site. Is everyone else thats experiencing this issue making frequent changes to their site? I'm just trying to start isolating the issue and collecting evidence to go to support with.

Im also having this issue. Has anyone got any solutions to speed up the checkout process from the cart.

I'm not sure what can slow down the checkout page on every different store, but I suspect it's an asset that's blocking the page load. It could be a payment option's JS code, for example.

The first step is to open the Network tab in the DevTools and look at the waterfall column. It's an indication of how long these assets take.

I've seen 6 seconds to load even Shopify's own assets from their own CDN. And this varies with every device, internet connection etc.

A solution I can think of, is preload these assets even before the customer visits the checkout page. They would remain on the visitor's browser cache and be available during checkout load (someone mentioned this issue only on the 1st load).

When it comes to native preloading, you can't really do that without Shopify Plus.

And of course, that depends on what kind of asset we're talking about. Some of these might not allow caching.

Shopify is aware of these problems, I have an open ticket with developer support team, they are working on the issue.

I found out that requests to "" are the cause of the delays and problems at least for us it is like this.

Until Shopify starts pre-seeding the cart cache after the cache has been invalidated, our workaround has been to add to cart and go to checkout after every single change we make to our store. This includes changes to product descriptions, inventory etc. Pretty much everything seems to trigger it.

This must be resulting in a lot of lost revenue for Shopify and all of its merchants alike. Imagine how often store edits are made and how slow the first checkout is after each edit. Multiple that over millions of transactions and I expect the lost revenue is significant.

Might shopify charge extra for faster checkout?

Our Checkout speed is very slow as well.  We are converting less that half of those that reach CHECKOUT.  Our over conversion percentage has plummeted.  We can't stay on Shopify if this continues.  If there are any developments let us know.
