How can i speedup my quarto rendering?

[stefaniecg]

Description

Currently it takes about 1.5 hours for my report to generate.
Quarto uses only 1 CPU in my machine, is it possible to extend this to more CPUs?
Or is it memory? now is using 75% of my cache.

This is very slow, how i can improve this?
Or what configurations are known for slowing down rendering?

Thank you for the help you can provide.

This seems indeed quite a huge amount of time. Is this a single report?

First, what you need to look into is the computation. Which computation is done in your report? How is it done? How long does it take? How optimized is it?
Quarto won't do anything specific for computations: It will call R, Jupyter, or Julia, depending on the engine used, and run this in a background process. If the computation is taking a very long time and is resource-intensive, this is not a "Quarto optimization problem."
We don't have your report or more information on what you do exactly, and this would be the first place to look.

So please, try to identify how much of the 1.5 hours your computation code is taking. If this is a huge part of it, each language has tools to improve computation and run in parallel, for example.

Quarto will be responsible for triggering the computation and rendering the output, but do not optimize the computation part. There are workflows where using Quarto as the publication step at the end is the best option. This means doing all processing in an optimized manner outside of Quarto, saving results, and loading them as necessary in the report for Quarto rendering to be as efficient as possible.

Anyhow, we need more information to help you understand and help you with this 1.5-hour rendering report. This is indeed huge for a single report, so we assume you have very computation-intensive calculations in it, or that your environment may limit the computation part.

Thank you.
