Lion web browsing extremely slow for one site.

I am a moderator on the citizen science “Moon Zoo” forum and one of the tools we use to examine images of the lunar surface sent back by the Lunar Reconnaissance Orbiter is the ACT-REACT QuickMap Tool - found at http://target.lroc.asu.edu/da/qmap.html?mv=eqc&mcx=0&mcy=0&mz=1

When people find an image they want us to look at they often post an ACT-REACT link. These links are the problem. Under the Mac OS X 10.7.4 release, using the latest Safari (5.1.7) or Chrome (18.0) or Firefox (12.0) browsers, the images take ages (from 9 to 17 minutes) to load. Sometimes they don’t load at all.

The same ACT-REACT link will load in under a minute when using Mac OS X 10.6 (Snow Leopard) on the same machine - I have a second hard-drive containing Snow Leopard. None of the users of the forum using PC software have reported problems so looks like it's restricted to Lion.

Other web sites work fine, it is only this one site that I have problems with and only when using Lion.

The following ACT-REACT link is the one I used in testing: http://target.lroc.asu.edu/da/qmap.html?mv=eqc&mcx=3910780.30841&mcy=-615107.273 23&mz=11

When using Safari 5.1.7 to access the above link I get the following messages in the Error Console:

“Failed to load resource: The request timed out. fprovweb.exe” (this error displayed over 300 times)

Full image took 17 minutes to load.

Google Chrome 18.0 browser took 9 minutes to load the image.

Firefox 12.0 browser never finished loading.

This problem occurs on my Mac Pro and MacBook systems.

I have reported this on the Apple Feedback site.

What DNS settings are you guys using? I could see how that would be the problem; it appears the javascript has to go to another site to fetch stuff from a database (haven't done much analysis, but isn't the site a place where it stitches existing photos together for your viewing pleasure?

Also, here's a page with some java testing resources that might help. http://javatester.org/othertesters.html

I use both OpenDNS, as well as Google's DNS. DNS settings do not matter.

Let's refresh here ...

No matter what internet access point I use, no matter what DNS I use, no matter what my Java settings are, no matter which website I go to .... I still have this problem.

Even with a fresh reload, this problem persists. Just a quick google search shows I am not the only one.

Can I get my $4800 back please?
