Image Inconsistencies: How and When Browsers Download Images

CSS Wizardry

My only reservation was knowing that, because the images are defined in CSS rather than HTML, their outgoing requests won’t start until the browser has created the Render Tree: it’s not until all the CSS has been downloaded, parsed, and the CSSOM constructed that the browser actually knows This div with this class is currently visible on the page and its background is set to be this image: I’d better download it! we can’t download a background-image until we’ve built the CSSOM).

Media Query & Asset Downloading Results

Tim Kadlec

A little while back, I mentioned I was doing some research for the book about how images are downloaded when media queries are involved. The same as with the first test: every browser tested, aside from Opera Mini and Opera Mobile, will download the image. With the exception of the over-eager Fennec, every tested browser only downloads the image when needed. which dominates the Android marketshare, still downloads both images as does Fennec and the Kindle.

How to add you database to HammerDB – Pt2 Fork, clone and binary downloads

HammerDB

This can be done with Clone or download. in this example we will use the command line to do this using the web URL shown in the Clone or download link. As identified in the previous post we don’t have the correct bin and lib directory so need to download the binaries version from here. As noted in the previous post to add a database to HammerDB you will need to change the source code. There are different ways to do this, however the recommended way is as follows.

Media Query & Asset Downloading Tests

Tim Kadlec

Unfortunately if you’re not careful, this can lead to multiple images being downloaded even when they aren’t being used. A few people—including Jason Grigsby , Greg Rewis and Aaron Mentele —have done some excellent testing about how images are downloaded when media queries are involved. The property (which appears to be well supported) returns true if the image has been requested and downloaded, and false otherwise.

The Performance Inequality Gap, 2021

Alex Russell

As networks have improved, client-side CPU time now dominates script download, adding further variability. TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB.

CSS and Network Performance

CSS Wizardry

CSS is critical to rendering a page—a browser will not begin rendering until all CSS has been found, downloaded, and parsed—so it is imperative that we get it onto a user’s device as fast as we possibly can. download any CSS needed for the current context (medium, screen size, resolution, orientation, etc.) with a very high priority, blocking the Critical Path, and; download any CSS not needed for the current context with a very low priority, completely off of the Critical Path.

The Fastest Google Fonts

CSS Wizardry

Thus, on a 3G connection, it takes over nine seconds to download each file. Conversely, the median download time for the CSS file was just 9.5ms—it took 148× longer to get to the headers of the file than it did to download the whole thing.

Bandwidth or Latency: When to Optimise for Which

CSS Wizardry

Generally speaking, increased bandwidth is only particularly useful when you’re transferring or downloading large files. In the Time column: The top value is total time taken from dispatching the request to having downloaded the entire response. There are a lot of different phases involved in getting from the point of requesting a file until we’re able to begin downloading it. It took only 3ms to download this file, yet 74ms to negotiate the network.

When CSS Blocks

Tim Kadlec

Preload is a bit of a blunt instrument—whatever you apply to it is gonna jump way up in line to be downloaded. If CSS is still being downloaded, inline scripts won’t run until that CSS arrives.

In-Browser Performance Linting With Feature Policies

Tim Kadlec

With the oversized-images policy in place, large images are still downloaded, but placeholders are shown instead, and an error is logged to the console. Without those in place, the browser has no idea how much space the image should take up until the image has actually been downloaded.

The Cost of Javascript Frameworks

Tim Kadlec

The thing about JavaScript is you end up paying a performance tax no less than four times: The cost of downloading the file on the network. The cost of parsing and compiling the uncompressed file once downloaded.
