“Clean” Code, Horrible Performance

Re:“Clean” Code, Horrible Performance by gary_0 on Tuesday February 28, 2023 @05:05PM (#34975585)

I just loaded cnn.com while looking at the CPU utilization graph: 50% use of my 8 logical cores at 4.5GHz for the better part of a second. So no, it's not just network latency. Doing multiple parallel network requests, parsing, doing layout and applying styles, running scripts, decoding media... a modern website and browser devours CPU time.

Jira cloud famously takes 30-60 seconds on even a fairly high-end laptop, which is just staggering. I can install an entire operating system into a virtual machine in that time.

I use Jira every day and, no, it does not take 30-60 seconds to load a page.

The hyperbole in this comment section is something else. Either that or people are using 15 year old computers to browse the web.

I see 30-seconds delays in a vanilla project on Jira cloud sometimes. Hardware was expensive in 2019.

So those who visit Fox and CNN are helping to destroy the planet. Or is it the developers fault? Can't be the developers.

one of them must be to blame! readers and publishing engineers famously sit atop corporate decision-making hierarchies, and no one else in a mass media enterprise ever did anything wrong, certainly not before the web was a thing

I was about to dispute what you said, but I realised I was running uBlock origin. What machine and browser are you using? I just used Chrome (on MacOS using an M1 Pro CPU) to run a performance profile and loading cnn.com took the following:

- Loading: 29ms with uBlock vs 42ms without

- Scripting: 548ms vs 1850ms (!!)

- Rendering: 42ms vs 105ms

- Painting: 8ms vs 29ms

- System: 216ms vs 295ms

- Idle: 460ms vs 8707ms

Holy shit, advertising and trackers are absolute resource hogs.
