I was under the impression that there would either be problems or less than acceptable results presently with Java apps/applets so the results may not be as impressive (yet). The Java Applet Plugin Enabler and Java Applet.plugin (/Library/Internet Plugins) are not Universals, they are still PowerPC.

Here are the relevant stats:

I understand the frustration, my point is to show that there might be something else causing the problem.
I know that with computers we can not think linearly.
Some people are reporting problems with QT. I do not have any problems with QT. I was just checking the Apple QT site to view trailers. Not just it works, it does it beautifully.
This is not to invalidate your points, but to make us look somewhere else, maybe.
My iMac has been constantly getting the speeds I've shown you. The G4 got the best one just before I sent the data.

I suggested to someone else I'll suggest it to you, if you want, we can check system against system to see what is going on.

By the way, did you check your console for any info? If not, do it.

Deivy

GW, I've posted some of my hardware setup in here.

Check to see if anything there gets your attention.

By the way Console demands a lot of patience, as I was checking for a website to see if I could stream WMP (I can) I would not get that particular site to work. Checking Console I found:
"Assert failed: /Users/dave/dev/flash/player/FlashPlayer/platform/mac/plugins/../../../core/spl ayer.cpp:21993"

I need the flash player plugin. It is not installed and I do not know if it works on iMac DC.

I'm getting lots of rather strange console messages,
but that is not all that unusual. Nothing there
looks like network generated or caused stuff.

I don't any problems with QT either, others say that
it doesn't work.

It's not QuickTime per se (at least for me and many others) it's QuickTime streaming. Movies loading from Apple's site (or others) are fine but ones that are stream ended up failing. The same stream works perfectly with a PPC Mac running 10.4.4 and QuickTime 7.0.4. Apple tech says there it is a known issue and is being looked at. Oh well....

What access points are you using?

I have the exact same program with an iMac core duo 17''. The wireless speed is way too slow. Wired it is fine. Through my airport express an internet download goes at 1/100th the wired speed. It is not my airport express because there are a number of laptops Powerbooks and Dells that use the access point with no speed loss. It is only the iMac core duo. I have also gone through all the logical tests of what could cause this, and it all points back to the airport card/drive for the core due. Please let me know if there is a fix for this.

Thank You,
Scott

I'm not familiar with the Airport Express - does it support wireless security (WEP, WPA etc...) and if so, do you have it enabled? THat may or may not be the issue although in my case, having WPA turned on (I tried two different routers - a D-Link and Belkin) resulted in bandwidth chokes. Ever since turning security off, my bandwidth has returned to normal levels. This problem did not occur on G4's with Airport cards.

I did a web chat with an Apple support agent about this any he wasn't aware of the issue (although is now). Hopefully this issue will be tracked down soon (although using MAC addressing and no SSID broadcast has alleviated my security concerns).

On a side note, the iMac CD still rocks!!! I already have 3 co-workers and a family member (3 of 4 being Windows users) looking to buy one! Good job Apple!

I have a similar problem, but with a twist. I have a new 20" iMac core duo and a new 17" (for work). The 17" wireless connection seems to be working fine, but the 20" connection was running at about 1/5 the speed (comparing download rates). I did not notice any oscillation in the 20" download rate. I have a d-link di-624 router and an airport express extending the network. Airtunes was also really pokey for the 20" but not the 17".

I talked to an apple tech last night and ran the 20" just on the airport express with no problems. Now I have it back on the d-link router with no encryption and updated firmware and it is working fine. The next step is to get the encryption back up. I had WPA-PSK encryption through the router.

The tech could not explain why the 17" and the 20" behaved differently, even though they were sitting side by side.

I don't seem to be having this problem,

over wireless network, netgear router, all laptops and pcs, connected to the network are getting 1200 kps, and 325 kps upload speed.

The new 20" intelimac is getting exactly the same, 1180 and 320. I have tried the speakeasy, and the miranda, miranda was about 5% slower, but I didn't test it on the other devices.

Through the network, so device to device I get about 1-2 mbs.
