Today, we’re launching four improvements to Pages that bring functionality previously restricted to Workers, with the goal of unifying the development experience between the two. Support for monorepos, wrangler.toml, new additions to Next.js support and database integrations!

30 seconds of CPU time

Walshy•4/7/24, 12:41 PM

And you can set a lower limit if you wish on the dashboard

Walshy•4/7/24, 12:42 PM

10ms is I think still the limit for free plan

Walshy•4/7/24, 12:42 PM

Otherwise you're on Standard with 30 seconds

Isaac McFadyen•4/7/24, 12:42 PM

Keep in mind this is CPU time

Walshy•4/7/24, 12:43 PM

Isaac any idea if free is still 10ms?

Isaac McFadyen•4/7/24, 12:43 PM

?cpu-time

Flare•4/7/24, 12:43 PM

CPU Time: the amount of work the CPU needs to do, measured in msms. More CPU-heavy things will increase it (for example, hashing passwords). This is not the same as the time a

fetch

fetch

request takes.
Wall Time: the actual amount of time a Worker runs for, as though you measured it with a clock or your browser DevTools

WWalshy Isaac any idea if free is still 10ms?

Isaac McFadyen•4/7/24, 12:43 PM

I believe it is, yeah.

AAnay-208 Ya so cpu time would be cpu * duration, right? how much is the cpu then

Isaac McFadyen•4/7/24, 12:44 PM

CPU time is the amount of work the CPU does, it's not the same as duration.

Walshy•4/7/24, 12:44 PM

Isaac McFadyen•4/7/24, 12:44 PM

You can have a Worker running for 30s but only use 10ms CPU time, or have a Worker running for 100ms but use 2s of CPU time.

Isaac McFadyen•4/7/24, 12:45 PM

It just depends on what you're doing in the Worker (or Function) itself.

Walshy•4/7/24, 12:45 PM

Duration is not related. It's simply an amount of time of actual compute

Hello, I’m Allie!•4/7/24, 12:49 PM

CPU Time can never be higher than Wall-Time tho? Unless you count calls to other services?

Isaac McFadyen•4/7/24, 12:50 PM

I believe (correct me if I'm wrong) that CPU Time is measured in relation to running a single core at 100%.

Isaac McFadyen•4/7/24, 12:50 PM

10s of CPU time = 10s of running a full core at 100%

Isaac McFadyen•4/7/24, 12:50 PM

And if you're calling out to stuff in C++ land like hashing I expect it to use multiple cores?

Isaac McFadyen•4/7/24, 12:50 PM

I might be wrong though

IIsaac McFadyen And if you're calling out to stuff in C++ land like hashing I expect it to use m...

Hello, I’m Allie!•4/7/24, 12:52 PM

Oh, you meant CPU Time in general. I was referring to specifically on CF, where you only get single thread(unless you call out to a DO or smthn)

Isaac McFadyen•4/7/24, 12:52 PM

On multi-processor machines, a computer program can use two or more CPUs for processing using parallel processing scheduling. In such situations, the notion of total CPU time is used, which is the sum of CPU time consumed by all of the CPUs utilized by the computer program.

HHello, I’m Allie!Oh, you meant CPU Time in general. I was referring to specifically on CF, where ...

Isaac McFadyen•4/7/24, 12:53 PM

Yeah your isolate gets single-thread

Isaac McFadyen•4/7/24, 12:53 PM

But I expect things in

workerd

workerd

internally, like calculating hashes and stuff, are multicore themselves?

Isaac McFadyen•4/7/24, 12:53 PM

I don't know though.

Hello, I’m Allie!•4/7/24, 12:54 PM

I would hope that you aren't billed for multicore ops because they are an implementation detail?

Isaac McFadyen•4/7/24, 12:54 PM

Well you're billed for the amount of CPU time you use.

Hello, I’m Allie!•4/7/24, 12:54 PM

It would make it pretty difficult to figure out what your pricing might be

Isaac McFadyen•4/7/24, 12:54 PM

It uses the same CPU time on a single-core vs multi-core.

Isaac McFadyen•4/7/24, 12:54 PM

Just multi-core uses less wall time because it's usually faster.

Isaac McFadyen•4/7/24, 12:54 PM

Might be a good question for workerd-runtime though

IIsaac McFadyen It uses the same CPU time on a single-core vs multi-core.

Hello, I’m Allie!•4/7/24, 12:54 PM

Oh, I thought you said it multiplies it by number of cores?

HHello, I’m Allie!Oh, I thought you said it multiplies it by number of cores?

Isaac McFadyen•4/7/24, 12:55 PM

No, so if you cap 4 cores at 100%, then in 1 wall-clock second you'll consume 4 cpu-time seconds.

Isaac McFadyen•4/7/24, 12:55 PM

But if you wanted to do the same task on a single core, then you'd cap that single core at 100% for 4 wall-clock seconds and consume the same 4 cpu-time seconds (assuming the scaling was linear)

IIsaac McFadyen No, so if you cap 4 cores at 100%, then in 1 wall-clock second you'll consume 4 ...

Hello, I’m Allie!•4/7/24, 12:56 PM

I was also just referring to while you can pretty easily figure out single core pricing, by timing total duration length, then subracting I/O, it would be a bit more complex for multicore

HHello, I’m Allie!I was also just referring to while you can pretty easily figure out single core ...

Isaac McFadyen•4/7/24, 12:57 PM

Yeah... I'm not sure.

Hello, I’m Allie!•4/7/24, 12:57 PM

Since while a request may take 5 cores 10 seconds to process, you don't know if it is utilizing all 5 cores the entire time

AAnay-208 How to see cores capped then?

Isaac McFadyen•4/7/24, 1:00 PM

Sorry, I kind of went on a tangent - this isn't related to your use-case at all.

Isaac McFadyen•4/7/24, 1:00 PM

You just need to look at the CPU Time measurements on the Cloudflare dashboard. On the free plan you get 10ms of CPU time, on the paid plan you get up to 30s.

Fun fact: you could create next-on-pages projects without needing to do additional setup for a long time. The pages project create command accepts a compatibility flags argument which automatically sets the flag in your new project

lunaOP•4/7/24, 2:29 PM

huh? that doesn’t answer the question at all.

James•4/7/24, 2:46 PM

kind of. you said you can't push a next-on-pages project without having to set it up in the dashboard, but it's always been possible to do that have the compat flag added when creating the project. sorry, not a helpful response to you i know.
