(Relatively) high latency compared to other services

Rowin · 2024-04-07T18:47:46.689Z

I noticed that Cloudflare Pages latency is (relatively) quite a bit high compared to Vercel and Netlify. I sent 100 requests to each of these providers and measured the latency to download a txt file containing just `Hello!`, only counting requests that used an already established connection to the server: Vercel: ``` 95th Percentile: 23.9ms 50th Percentile: 9.9ms ``` Netlify: ``` 95th Percentile: 7.9ms 50th Percentile: 6.8ms ``` Cloudflare Pages: ``` 95th Percentile: 82.3ms 50th Percentile: 52.6ms ``` This is from a VPS from Hetzner in Germany. I get similar results from my home connection in the Netherlands. How come Cloudflare Pages has the highest latency, given the amount of PoPs Cloudflare has? Don't get me wrong, I absolutely love Cloudflare Pages, just wondering if there's something unusual going on here.

As far I understand. because you query the database. so it is better to have server close to database (like Vercel and Netlify, they use Serverless Function AWS Lambda under the hood) than the server close to user (like Cloudflare Worker for example). You can watch a video of Fireship explain about this (from 2.32):https://www.youtube.com/watch?v=yOP5-3_WFus

Is "edge" computing really faster?

Edge computing is becoming a popular way to deliver modern web applications. Let’s find out if the Edge is really faster by comparing Firebase to Vercel Edge Functions with Next.js.

This is from a VPS from Hetzner in Germany. I get similar results from my home connection in the Netherlands. How come Cloudflare Pages has the highest latency, given the amount of PoPs Cloudflare has?

Pages uses KV for static assets. KV only has two central stores, one in EU, one in US, and the rest of the locations just cache the value. More requests, more cache hits, less latency.
I'd also check which location you are hitting. You can go to

/cdn-cgi/trace

/cdn-cgi/trace

/cdn-cgi/trace

/cdn-cgi/trace path and look at

colo=

colo=

colo=

colo= to see airport code of location you are hitting. https://developers.cloudflare.com/ for example is a Pages Static Site with high traffic (and Enterprise routing).

By "the rest of the locations just cache the value", do you mean the regular Cloudflare CDN cache, or something KV specific? Asking because I didn't notice the latency going down after a bunch of requests. Makes sense if it's the former, because I was sending requests to the

pages.dev

pages.dev

pages.dev

pages.dev domain, which doesn't cache(?).

I already checked the colo and it was fine, my bad for not mentioning it.

RowinOP•4/9/24, 2:31 PM

Seems like you meant the latter, judging by this page: https://developers.cloudflare.com/kv/reference/how-kv-works/

Chaika•4/9/24, 2:31 PM

It's pretty close to the normal cdn cache, being colo specific, but not exactly it. It's on both pages.dev and custom domains, ignore cf-cache-status.
I would be curious what your latency is to something completely on edge like https://cloudflare.com/cdn-cgi/trace
~50ms is pretty high for cached results

hmm yea it's semi-known cf cache is faster then pages internal cache but that's a pretty decent jump

C

Chaika•4/9/24, 2:47 PM

pages does have to go cf for saas -> invoke worker -> kv cache (which is slower on its own)

R

RowinOP•4/9/24, 2:51 PM

My thoughts exactly. worker processes are reused across requests when possible though, right?

C

Chaika•4/9/24, 2:51 PM

ehh not really and I doubt workers themselves are the issue

R

RowinOP•4/9/24, 2:51 PM

And all the requests except the first are using an already established TLS connection, so it's probably safe to rule out CF for SaaS

C

Chaika•4/9/24, 2:52 PM

Well if you have keepalive on, you'd keep hitting the same isolate

R

RowinOP•4/9/24, 2:52 PM

Yep

C

Chaika•4/9/24, 2:52 PM

Workers share the same process for multiple isolates/customers though, the isolation is isolate-level, not process-level (except in some cases, docs do a good job of explaining it: https://developers.cloudflare.com/workers/reference/security-model/)
