Chrome Speed vs Potato/Soundwaves/Lightning

Chrome goes head to head in a speed test vs a potato cannon, sound waves and lightning

YT:
These speed tests were filmed at actual web page rendering times. If you're interested in the technical details, read on!

Equipment used:

- Computer: MacBook Pro laptop with Windows installed
- Monitor - 24" Asus: We had to replace the standard fluorescent backlight with very large tungsten fixtures to funnel in more light to capture the screen. In addition, we flipped the monitor 180 degrees to eliminate a shadow from the driver board and set the system preferences on the computer to rotate 180 degrees. No special software was used in this process.
- 15Mbps Internet connection.
- Camera: Phantom v640 High Speed Camera at 1920 x 1080, films up to 2700 fps


"Why does allrecipes.com in the potato gun sequence appear at once, and not the text first and images second? And why does it appear to render from bottom of the screen to the top?"

Chrome sends the rendered page to the video card buffer all at once, which is why allrecipes.com appears at once, and not with the text first and images second. Chrome actually paints the page from top to bottom, but to eliminate a shadow from the driver board, we had to flip the monitor upside down and set the system preferences in Windows to rotate everything 180 degrees, resulting in the page appearing to render from bottom to top.

"Why does the top one third of the page appear first on the weather.com page load?"

Sometimes only half the buffer gets filled before the video card sends its buffer over to the LCD panel. This is because Chrome on Windows uses GDI to draw, which does not do v-sync.

"The screen wipes are so smooth - how was that achieved?"

The screen wipes up in a gradated wipe because LCD pixels take around 10ms to flip and gradually change color.

I love Chrome very much and for the typical web surfer I wouldn't argue that it should be their #1, go-to browser, especially compared to Internet Exploder.

But a week or two ago I tried for days very hard to switch to it from Firefox and for my needs, it comes up short and does not beat out Firefox despite its lightning fast V8 JavaScript engine and alleged better memory management.

As fast as Chrome is, it crashed on me several times during routine tasks, it does not have any print preview support, and FireBug, my preferred tool for JS debugging, does not work so well (example: the web page's scrollbar includes the FireBug window, so I can't view the bottom of the page without undocking FireBug; the extension is also incomplete as compared to the Firefox version). I actually found myself repeatedly switching over to FF to load my development pages just for some proper debugging.

In addition to all that, the AdBlock extension is not able to block ads until after they've been downloaded. This results in ads showing up momentarily before they disappear from the page and often the space for the disappeared ads remains, whereas in FF they just never appear at all.

One other less significant issue is that you can't use address bar shortcuts for bookmarks, e.g., in FF I could type "w aaron burr" and it would load WikiPedia.

Finally, the lack of a way (at least an obvious way) to search a specific site is a bother. E.g., in FF I hit CTRL+E to get to the search box then CTRL+downarrow to switch to Amazon, then type in my query and, boom, I'm at Amazon. You can also add VideoSift to that search box in Firefox; if you don't know how, click the search box icon then click "Add VideoSift Search". (Note: in Chrome you can type "amazon" [among others] then hit TAB for a site-specific search, but that feature's not available for all sites and I don't see a way to add others.)

The end. (What is this my own personal blog or something?)

Chrome is fast, but is currently limited on features. It also has problems remembering passwords for some sites while others work fine. I prefer Firefox for "normal" computers and large monitors.

Chrome is ideal for netbooks though. It loads fast, doesn't take much memory, and has the largest viewable area of any browser I've tried. Hopefully it won't get bloated as Google fills in missing features.
