We're experiencing consistently high latency (~1000ms) when using the Cloudflare KV REST API for bas

We're experiencing consistently high latency (~1000ms) when using the Cloudflare KV REST API for basic key-value operations in our authentication flow. This seems excessive compared to the expected performance of KV storage.

Our implementation uses standard API calls following your documentation:

GET/PUT to
```
https://api.cloudflare.com/client/v4/accounts/{account_id}/storage/kv/namespaces/{namespace_id}/values/{key}
```
https://api.cloudflare.com/client/v4/accounts/{account_id}/storage/kv/namespaces/{namespace_id}/values/{key}
```
https://api.cloudflare.com/client/v4/accounts/{account_id}/storage/kv/namespaces/{namespace_id}/values/{key}
```
https://api.cloudflare.com/client/v4/accounts/{account_id}/storage/kv/namespaces/{namespace_id}/values/{key}
Authentication via X-Auth-Email and X-Auth-Key headers
Small data payloads (<2KB)

Is this latency (1 second) expected behavior for the REST API endpoint? If not, are there known optimizations, best practices, or alternative approaches you'd recommend to reduce this latency to more reasonable levels for an authentication system?

Rest API latency is fairly expected because the REST API is located in a few core locations and all requests must travel through those locations before hitting the end service.

Isaac McFadyen•3/3/25, 4:51 PM

In the case of KV, a lot of the benefits come because of the caching done at the edge colos where the data is retrieved from, which doesn't happen with the REST API either iirc

Isaac McFadyen•3/3/25, 4:52 PM

Your best bet might be creating a Worker that uses the KV binding (even if it's a single Worker that just services a similar API as the REST API does)

Write a Worker that implements an API for you to call

Thanks. Let me check.

~~KV listing in the dashboard seems to be broken?~~

~~namespaceId: 1febbc2176164bb28d7cd90ab661e8621febbc2176164bb28d7cd90ab661e862~~

edit: the only fix was recreating the namespace

~~all these list ops come from a few minutes at the dashboard~~

Castio•3/5/25, 10:33 PM

hey everyone, I have a nextjs app that is a worker. I also have a binding for KV ready. How can I use it directly with binding in the app? KV store in NextJs App I decribed it in more details here

zegevlier•3/6/25, 10:11 PM

I don't think it's possible to do that. If your worker only does KV reads/writes, perhaps turning off the routes there could be a solution?

zegevlier•3/6/25, 10:12 PM

If your worker does more, I don't really have a good solution for you :/

1984 Ford Laser•3/6/25, 10:16 PM

Put auth on the Worker so a bad actor can't access it?

1984 Ford Laser•3/6/25, 10:17 PM

Per user rate limiting of some kind then perhaps

1984 Ford Laser•3/6/25, 10:23 PM

What do you mean? You said you wanted to avoid KV reads
Something like this depending on how much effort you want to go to: https://developers.cloudflare.com/durable-objects/examples/build-a-rate-limiter/

1984 Ford Laser•3/6/25, 10:40 PM

Then you'd need to implement something client-side, which doesn't render my suggestion useless, just wouldn't be using Workers to do so

1984 Ford Laser•3/6/25, 10:55 PM

How is your site hosted, on CF with Workers/Pages? What is the KV storing, and how is the client-side accessing it?

1984 Ford Laser•3/6/25, 10:58 PM

Sounds like you need to host the site on Static Assets which would be free unlimited requests if you are serving static HTML files

1984 Ford Laser•3/6/25, 10:59 PM

Could you store in D1 for way more reads?

1984 Ford Laser•3/6/25, 10:59 PM

What is the data on the pages?

1984 Ford Laser•3/6/25, 11:01 PM

Like I said, if you aren't invoking a worker at all then Static Assets are free and unlimited

1984 Ford Laser•3/6/25, 11:01 PM

Yeah that wil help for sure

It's not a bad suggestion from @1984 Ford Laser if you're willing to go the route of SSG - you'd never have to worry about a request bill

1984 Ford Laser•3/6/25, 11:09 PM

Blog seems like a perfect use case for Static Assets, especially if it isn't a big site. If you aren't adding pages regularly, in theory, you could load your current pages via Workers/KV, save them as HTML, then serve those pages using Static Assets. I'm simlifying a bit, but there are ways forward here
