Sadly, I find that chromecast (under google chrome) performs much better under Windows 7 than under Fedora-22 (on the same laptop). Under Fedora the reception is very jumpy. Admittedly this is with a rather low - 6.5Mb/s - internet speed.
I wonder if this is a common experience?

Not having any problems here in Taiwan.

What is your broadband speed?

Doing what exactly? AFAIK Chromecast connects directly to the Internet for supported applications (e.g. Netflix), so the OS on your computer shouldn't be an issue. If you mean sending web video from your desktop then of course that's a different matter, but there are a lot of variables (browser, codec support etc.) that aren't related to Chromecast.

I was watching live TV online, running google chrome on my laptop, first under Fedora-22 and then under Windows 7 (through filmon.com) using chromecast to cast the program onto a Samsung TV (series 6).
My laptop is linked to a router by WiFi, and thence to a CentOS-7 server, and finally to the internet.
You seem to suggest that the chromecast connects the TV directly to the router once the connection is established? That seems plausible, but doesn't explain the difference in quality.
I just tried using a Samsung Galaxy phone in place of the laptop to cast the same online TV program to the TV, and found this was actually even better than Windows. So I'd have to say Android wins the 3-way race.
I suspect my broadband speed (in central Italy) of 6.6 Mbps is on the borderline for this use, though that may be nonsense.

When using chrome to cast a tab like I'm sure you're doing then the traffic is coming from the source, to your browser, and then "reflected" to the chromecast dongle.
If you are using an application which is chromecast enabled, such as NetFlix or many of the chromecast enabled Android apps, then yes the traffic will be switched/configured to come from the source and go directly to the chromecast dongle.
This is the reason I can't cast Netflix from my Android Tablet to my TV. While my tablet is using a DNS proxy to redirect traffic to my VPN provider when casting the Netflix app notifies Netflix to switch but in the process my real IP address is exposed and Netflix then "knows" I'm not in the US. (I have a Roku to, so no worries...and there are other ways I could use the chromecast if I wanted to take a few extra steps).

Oh, BTW, I just got my bill and I actually have 20Mb/s download speed. :-)

Yes, it seems more complicated than I thought; I found when I started casting from my Android phone I could switch off the phone and the cast continued, so it must be going directly from router to TV. In fact I had to switch off the TV to break the connection. But this was using a filmon app on the phone which I'm sure is chromecast-enabled as you say.
So the difference in quality between Fedora-casting and Windows-casting may arise from different chromecast plugins for google chrome? But in both cases I am able to break the connection from the laptop.

That's interesting, and relevant in my case as I thought of subscribing to a VPN server in the UK as most UK online TV services seem to be restricted to users believed to be in the UK.

Can you tell from your bill? Mine says "up to 40Mb/s", but when I asked my ISP said he was surprised my speed was so high!

I use the LiveNow!TV app which is what I think you are using. It has built-in support for ChromeCast. For apps on the Android which don't have built-in your choice is to use ChromeCast's screencast or Screencasting to a SMARTtv. In those later cases there is the "reflecting" going on which would have an effect on performance.

Yes. See above.

There would be no problem if I were to be using a pure VPN connect established by my tablet or by my router. It is only a DNS proxy situation that doesn't work with Chromecast. I could use DNS proxy + screencast but that brings in the performance issue which may be a problem with a tablet.
I'm just too lazy to create the VPN connection on my tablet..2 extra touches...when I can just use my Roku. I sometimes think the extra touches may be worth it since the Netflix interface of Roku is "minimal".

Yes. It is 20, I'd just forgotten since I switched carriers about 2 years ago. I tested it and am getting the download speed I'm paying for. No trouble to stream simultaneously several sources.

It's not only plausible, it's how Chromecast actually works. A Chromecast is not just a Wifi dongle, it's a Linux computer with its own network connection. It simply uses the app on your phone, tablet or desktop as a control interface, but for "Chromecast-supported" apps the actual media processing is being done internally. When you don't have an appropriate app you're casting a browser tab to the Chromecast, so the work is being done on your desktop (or phone, etc.). The difference in quality is probably related to the way this is handled under the respective OSes, but there are multiple ways that could be affected, e.g. available codecs, networking protocols, browser versions, ... (I'm just guessing here as I haven't looked into it; I use an Amazon Fire stick because of the cool remote and because I got it cheap :-)
I just tried using a Samsung Galaxy phone in place of the laptop to cast the same online TV program to the TV, and found this was actually even better than Windows. So I'd have to say Android wins the 3-way race.
There you go. The phone and the Chromecast understand each other better. Maybe they even use a specialized protocol for this.

I doubt it has any effect, though if it's HD TV content 6Mbps is on the low side.
