[Microsoft Surface] wardh:
Hello, I have a simple question.

My Surface connects to the router (ASUS RT-N66U) with link speed 270Mbps. When I copy files between the Surface and my Win8 desktop I get 4-5MB/s (~40mbps) in transfer speed. Is that all the Surface can manage? My laptop gets 25+MB/s (450Mbps link speed).

Can someone try and post results here?
[Microsoft Surface] Dane Reynolds:
Upload speed?
[Microsoft Surface] wardh:
I'm on my home network coping a file from my PC to my Surface over wifi. I am not doing it over the internet.
[Microsoft Surface] GoodDayToDie:
Why are you assuming the Surface or the network is the bottleneck? Try the transfer between different devices (Surface and laptop, Surface and desktop, laptop and desktop, etc. Also try downloading a file over the Internet if your connection is fast enough that it won't bottleneck that (some people have such connections...). Try over different WiFi connections if possible.

The first step when you find a problem is to isolate it.
[Microsoft Surface] schettj:
I can push/pull 5-6MB/sec over 802.11n (2.4 or 5ghz) which seems to be the disk speed limit when using a class 10 SD card.
[Microsoft Surface] wardh:
Thanks for answering but did you even read my post? ? Anyway, Laptop to Desktop PC is ~5 times faster over the same WiFi network.
[Microsoft Surface] wardh:
Thanks, we get the same. If I copy a file from my sd card to internal memory I get 19MB/s so I don't think it's about disk speed.
[Microsoft Surface] apatcas:

[Microsoft Surface] Trig0r:

It's strange that they decided to add something else to the soc.
[Microsoft Surface] wardh:
But I was copying the file to internal and not to sd card.
[Microsoft Surface] wardh:
Would you mind trying to copy a file over WiFi and share your speed results?
[Microsoft Surface] apatcas:

[Microsoft Surface] schettj:
Yep, tested mine. Read/Write doesn't matter, maxes out at ~5MB/sec - even on a "270 mbit" 802.11n 5ghz link with 5 bars signal.

So I guess that's as fast as the arm cpu can push bits.
[Microsoft Surface] hwalker84:
Mine has the same problem. Even Speedtest.net maxes out at 5MB. My Nokia 920 has better results from the speedtest app. This person (7th Post) has a lot fast than what I'm getting

http://www.surfaceforums.net/forum/microsoft-surface-general-discussion/3110-slow-wi-fi-surface.html
[Microsoft Surface] schettj:
No they don't - their speedtest shows 2/1.7MB second, which is 20/17Mbit. You and I and most people are seeing between 40-50Mbit/sec transfer speeds on your local network, which is not horrible for 802.11 wifi

This is a pretty good description of maximum throughput on 802.11

http://www.buffalo-technology.com/en/wireless-802-11-technologies.html

We're getting close to max speed for 802.11a or g at 5MB/sec (~50Mbit) - it's possible to get better performance out of 802.11n but you've GOT to use wide channel mode (in 2.4ghz) or 5ghz mode with multiple antennas (2T2R,or better mimo - http://en.wikipedia.org/wiki/MIMO) to essentially double/triple up your channels. Apparently (and not shocking at all) the surface might only have 1T1R
[Microsoft Surface] GoodDayToDie:
For the record: a Byte is eight bits. 2/1.7 MBps is merely 16/13.6 Mbps.
[Microsoft Surface] wardh:
The network controller in Surface is a Marvell Avastar 88W8797. An 802.11n 2x2 dual-band system-on-chip (SoC) offering Wi-Fi data rates up to 300Mbps.

http://www.techrepublic.com/photos/...=72&tag=siu-container;thumbnail-view-selector

http://www.marvell.com/wireless/avastar/88W8797/
[Microsoft Surface] schettj:
So 2T2R on the chip. Assuming they enabled both antennas. 300Mbps wifi still only works out to 150mbit in each direction (because that's how they rate wifi) and real world throughput on a "300 mbit" link is no better than mid 60mbit with wide channel enabled or over 5ghz.

So, again, it's still in the ballpark for "average" performance over wifi, even with "300mbit" link speed.
[Microsoft Surface] wardh:
Where did you read that a 300Mbps connection is 150Tx + 150Rx? A 300Mbps link connection should have a throughput of ~150Mbps i optimal connections. Close to the router with full bars we should get ~100Mbps but we only get ~40Mbps on the Surface.
[Microsoft Surface] schettj:
There are NO wifi links that report 300mbit link layer that get anywhere near 100Mbps. Show me one.

Typical 300Mbit link layer will give you well under 70Mbit. The 40-55mbit you get on the surface is, while not stunning, certainly typical.
[Microsoft Surface] wardh:
I'm one floor above the router now and my laptop has 217Mbps link speed and I copy files with 14MB/s (112Mbps). But nevermind, I see now that 40-50Mbps is what I can expect from the Surface and that there is nothing wrong with my network. Thanks everyone.
[Microsoft Surface] schettj:
That is truly awesome speed.

Is this 802.11n 5ghz? What is the router and laptop. Honestly on 300mbit links I test out using iperf below 80mbit on several different access points, 40mbit wide 2.4 ghz, 5ghz, etc.

How do you measure that 112Mbps? Please consider (I am really interested) running iperf on two machines over the wifi link, to verify your speeds...

See http://www.smallnetbuilder.com/wireless/wireless-basics/30664-5-ways-to-fix-slow-80211n-speed for example showing 30Mmbit link speeds but 66Mbit actual throughput, measured speeds.

Edit2: MAX speeds on 5ghz 40mz, actual throughput results

http://www.smallnetbuilder.com/wireless/wireless-charts/bar/67-5-ghz-dn-40?see=MAX

This is what I am familiar with for wifi speeds.
[Microsoft Surface] wardh:
The hardware is nothing special. The router is Asus RT-N66U and laptop is HP Elitebook 8530w.

cnet has tested the router with iperf, they got 190Mbps on 5GHz.

http://www.cnet.com.au/asus-rt-n66u-339341721.htm
[Microsoft Surface] schettj:
And small net builder tested it and got 66mbit

http://www.smallnetbuilder.com/wire...al-band-wireless-n900-gigabit-router-reviewed

Note the "n900" designation, it's important. If you match this router with specific chipsets (which is what cnet did), it can get triple the throughput. BUT only if the connecting device is 3T3R and supports dual band 2.4/5ghz. Your laptop supports 3T3R and 450mbit link layer syncing, so it should get at least 50% more actual throughput than a 300mbit link layer... and you're seeing that.

The slower, more typical speed of 66mbit is what you'll get if you connect at "300mbit" (2T2R) at the link layer.

All that to say, the surface RT is giving wifi performance that would be expected for its hardware.
[Microsoft Surface] schettj:
here's iperf sending from and receiving to the surface rt with iperf on the rt:

[Microsoft Surface] e.mote:
>And small net builder tested it and got 66mbit

No offense, but single-number quote like this is pretty useless. If you look at the throughput table on pg 4 of the SmallNetBuilder review, there are a zillion throughput tests. Moreover, each of those tests is already an average of 6 different locations, each with varying distance and obstructions.

In short, because there are so many variables involved, the only way to compare relative wifi throughput is if you have the devices yourself, and run the same tests on each one. Your iPerf test is meaningless unless compared against another iPerf run. Each person will be in a different environment, which obviously is the dominant factor in wireless throughput.

Wifi throughput is not an easy thing to pin down, which is why vendors come up with the "add all the max link rate" numbers. At this point, I'd would aim for a good sale on a good 2x2 802.11n, because that's what most mobile devices (incl laptops) support. It's rare for a laptop to have a 3x2 or 3x3 arrangement.

It would be nice for SmallNetBuilder to test mobile devices, because that's where the action is, especially when WiDi and Miracast come into play later this year. The site is the most thorough and knowledgeable on wifi testing (Anandtech by contrast is sh!te). But I suspect the site don't have the connections to get loaner units to test.
[Microsoft Surface] schettj:
Yep, sorry - of course I ran iperf multiple times, and that is a representative number which covers my device and my router (a 3T3R router like the OPs)

It also matches iperf numbers I get from similar 2T2R devices in my home environment against that router, and is faster than 1T2R and 1T1R devices tested in the same environment.

*my* point is the Surface RT wifi performance seems to be on par with every other *similar* device's wifi performance. And to the point, the OP is comparing the 2T2R surface against a 3T3R laptop - and indeed it will be slower than that for wifi.
[Microsoft Surface] e.mote:
>*my* point is the Surface RT wifi performance seems to be on par with every other *similar* device's wifi performance.

The funny thing is no one ever bothered to do a comprehensive wifi throughput test for mobiles, when wireless speed is arguably the most important factor in mobile functionality. This leaves users to do their own nonsensical tests like running Speedtest.

My point is that since you are more familiar with this than the hoi polloi, then you should to relative comparisons with your own other devices--using iPerf or file copy or whatever--and move past the point of "seems to be." It would be a valuable data point to ascertain wifi performance for the Surface RT.

>And to the point, the OP is comparing the 2T2R surface against a 3T3R laptop - and indeed it will be slower than that for wifi.

Most mobiles now only have 1x1; only a handful have 2x2. Even at 2x2, their smaller antenna arrangement will always be worse than laptops. Likewise, only a handful of laptops have 3x3 antenna or 3x3 NIC. The HP Elitebook 8530w is a mobile workstation, hence its top-rated specs. The 2x2 vs 3x3 disparity is of small consequence in view of their relative rarity. But it does serve to highlight how far mobiles have to go to be the equal of laptops in a critical function. In that, it's a worthy test.

With WiDi and Miracast roll-outs this year, one hopes that 2x2 dual-band setups will be more popular this year for mobile. We'll see if MWC can provide some answers.

Hey Guys,

So i got my nexus 7 about a week ago and had noticed a touch response delay and it made scrolling through the homescreen and webpages a pain. I searched around last night and this morning and found these build prop tweaks.

#Response

debug.performance.tuning=1 - Increases touch responsiveness.

video.accelerate.hw=1 - Increases touch responsiveness.

windowsmgr.max_events_per_sec=150 - Increases scrolling responsiveness.

I aslo have fauxclock 123 installed from the play store and disabled the tegra 3 smart dimmer. After doing both i see a substantial increase in responsiveness. let me know if anyone else gets the same result.
