Hi Jim,

Try emptying the cache and reset Safari.

From the Safari Menu Bar, click Safari / Empty Cache. When you are done with that...

from the Safari Menu Bar, click Safari / Reset Safari. Select the top 5 buttons and click Reset.

Loaded for me in 1.5 seconds flat - so a bit slower than most sites I visit.

Something in your system is slowing down Safari.

The animation starts after about 30 seconds.

No jerky scrolling.

No increase in CPU usage.

Which of course doesn't really help you! 🙂

So, as something is holding up your safari, try the following:

(First, if yours is an Intel Mac, check that Safari is not running in Rosetta, which is enough to slow it to a crawl. If you are running Snow Leopard, run Safari in 32 bit not 64 bit.)

Do you have enough RAM? Less than 1GB can cause slowness. Is your hard drive too full? Less than 15%, or 15GB, of free space can also cause slowness.

Adding DNS codes to your Network Settings, should gives good results in terms of speed-up as well as added security:

Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:

208.67.222.222
208.67.220.220

(You can also enter them if you click on Advanced and then DNS)

(An explanation of why that is both safe and a good idea can be read here: http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 /

Open DNS also provides an anti-phishing feature: http://www.opendns.com/solutions/homenetwork/anti-phishing/ )

Wikipedia also has an interesting article about Open DNS:

http://en.wikipedia.org/wiki/OpenDNS

Whilst in System Preferences/Network you should also turn off 'IPv6' in your preference pane, as otherwise you may not get the full speed benefit (the DNS resolver will default to making SRV queries). If you want to know what IPv6 is:

This is Apple's guidance on iPv6:

http://docs.info.apple.com/article.html?path=Mac/10.5/en/8708.html

Click on Apply Now and close the window.

Restart Safari, and repair permissions.

If that didn't do it, then try this as well:

Empty Safari's cache (from the Safari menu), then close Safari.

Go to Home/Library/Safari and delete the following files:

form values
download.plist

Then go to Home/Library/Preferences and delete

com.apple.Safari.plist

Repair permissions (in Disk Utility).

Start up Safari again, and things should have improved.

Loaded fine and started animation quickly. In fact, my local Apple reseller has this very same web site displayed on one of their floor machines. Very impressive to customers they say.

I agree lkrupp that this is an impressive site.

My comments are about Safari's performance while displaying this site. The problem is scrolling and CPU usage. Scrolling because its jerky and if this site running in another window causes keyboard entry delay. CPU usage which on my MacBook turns into battery eating performance as the fans rev up toward 6,000rpm.

The picture looks great... impact on CPU usage has unintended consequences.

But I'm not seeing what you are describing on my system. Scrolling smooth, motion is not jerky, cpu usage does not spike. Just because you see this on your system does not mean everybody has your "issue". I don't see it at all.

If it helps advance this thread I get the same results as Jim when running Safari (latest) and Firefox.
