[Speed] is 25mbps enough?

I was wondering if 25mbps is enough for 3 people to stream Netflix at the same time assuming all 3 will be in HD.

DiffProbe release. January 2012. Build 1008.
Shaper Detection Module.

Connected to server 4.71.254.149.

Estimating capacity:
Upstream: 5605 Kbps.
Downstream: 26998 Kbps.

The measurement will take upto 2.5 minutes. Please wait.

Checking for traffic shapers:

Upstream: No shaper detected.
Median received rate: 5600 Kbps.

Downstream: No shaper detected.
Median received rate: 26544 Kbps.

What can 3 people do with speed like that at the same time? Reason I ask is it worth it for me to upgrade to 50mbps or will 25mbps be good enough?

Even 12 was enough for us. We did it in December 2 PCs + TV at the same time

I think Netflix (normal) HD is 5-6 Mbps per stream. This, in theory, means you'd be ok. But you can always try it and if it's insufficient upgrade later.

according to »support.netflix.com/en/node/306, you'll want to budget 5Mbps for HD streaming (7Mbps for super hd, which comcast doesnt "support" yet).

25/5 should be more then enough for 3 HD streams. I had no problem doing 2 HD streams over 12/1.5.

On Comcast the highest 1080P HD stream is ~4.3 Mbps (3.8 Mbps for video + ~400kbps for 5.1 audio) per stream as Comcast isn't using Open Connect so no 'Super HD'.

25 Mbps will be fine for 3 streams - we do it all the time on a 16 Mbps Comcast connection.

I was converting Netflix' own documented value:

Best quality (uses up to 1 GB per hour, up to 2.8 GB per hour if watching HD, or up to 4.7 GB per hour if watching 3D)

The 2.8 GB per hour could be referring to their "Super HD" I suppose. I thought their Super HD was higher than 6.3 Mbps, though.

Thought I would make it a little more accurate.

Netflix Super HD highest rate is 5800kbps video and 384kbps audio. Their 3D rate is higher.

If you can get Super HD they have an 'Example Short 23.976' title which shows the actual video bit rate. With Super HD and a fast enough connection it will ramp up to 5800 kbps (4300 kbps is the other Super HD video rate).

Note 'Example Short 23.976' doesn't seem to be currently available unless you are on a Super HD connection (which of course you won't be if you are on Comcast.....)

On Comcast the fastest you will see is HD at 3800 kbps video and 384 kbps audio.
