Mc3research Posted February 24, 2012 CID Share Posted February 24, 2012 Across several tests, I've achieved 25 - 29 Mbps in the following Topology: Browser = Terra 1.3.6 OS = IOS 5.0.1 Device = iPad2 CDMA, 64GB, dual core 1Ghz Apple A5 802.11n = 5Ghz 48(P) 44(S) @ < 10m, indoor, NLOS Access Point. = Netgear 3700 v1.0.7.98NA (dual band with Atheros 680Mhz RISC NWP) LAN = 1Gbps, CAT6 (1m) CPE = Motorola Surfboard 6120 v1.0.1.8-SCM02-NOSH ISP. = Suddenlink.net, 50Mbps/2Mbps nominal and verified avg latency. = 59.7ms (52B null packets at 10 pings/s) Traceroute to mytest.net, 64 hops max, 52 byte packets: hop(4) 36 bytes cdm-66-76-30-37.tylrtx.suddenlink.net (66.76.30.37) hop(5) 36 bytes 64.211.195.141 hop(6) 36 bytes ae2.csr2.dal2.gblx.net (67.16.151.82) hop(7) 36 bytes po9.ar5.dal2.gblx.net (67.16.151.133) hop( 36 bytes verizon-2.ar5.dal2.gblx.net (64.208.27.1) hop(9) 36 bytes 0.ae1.xl3.dfw7.alter.net (152.63.96.46) hop(10) 36 bytes 0.ge-7-3-0.xl3.mia4.alter.net (152.63.1.110) hop(11) 36 bytes tengige0-6-4-0.gw11.mia4.alter.net (152.63.84.130) hop(12) 36 bytes internet-gw.customer.alter.net (152.179.26.218) hop(13) ******************** Request timeout hop(14) 36 bytes 24.244.158.2 hop(15) 64 bytes 208.87.33.151 Best results are obtained with large file sizes (>= 25MB) Observations: 1.

I'll give terra a try next time I'm working on the iPad... I'll have to see this >50MB crash for myself. This is the best I've pulled on the iPad so far... ... But I was cheating because it wasn't really on an iPad. Rather my iMac running xcode's iPad preview. It really feels like an iPad though... how it loads. Best I've seen on my network with a real iPad was about 30Mbps... actually just under 30Mbps like you had. Maybe that's the limitations of the real device? I haven't tested them enough myself to be sure... maybe you can provide more iPad insight. -D Quote Link to comment Share on other sites More sharing options...
Mc3research Posted February 26, 2012 Author CID Share Posted February 26, 2012 ... But I was cheating because it wasn't really on an iPad. Rather my iMac running xcode's iPad preview.

Maybe that's the limitations of the real device? I haven't tested them enough myself to be sure... maybe you can provide more iPad insight. -D I'm just guessing that the I/O speed of a low power consumption 802.11 chipset may be the limiting factor. I also suspect that if the file was being written to disk, the throughput would have been much lower. It is, however, fast enough to demonstrate that with the right server and network config I can deliver 20 channels of SD and 10 channels of HD to multiple 802.11n devices in range. (more if I use 5Ghz and 2.4Ghz simultaneously.). But this is pushing the limit of staying on topic for this forum.... Mike Quote Link to comment Share on other sites More sharing options...
Mc3research Posted March 2, 2012 Author CID Share Posted March 2, 2012 I'll give terra a try next time I'm working on the iPad... I'll have to see this >50MB crash for myself. Before you get around to test, D/L Logviewer on the iPad. This will give you some degree of info on what happened. (It's also nice to have some minimal glympse inside the Walled Garden.) :::.. Download Test Results ..::: Download Connection:: 18824 Kbps or 18.4 Mbps Download Test Size:: 50 MB or 51200 kB or 52428800 bytes Download Speed:: 2353 kB/s or 2.3 MB/s Tested At:: http://TestMy.net version:12.3 Validation Link:: https://testmy.net/db/Cl746XE Test Time:: 2012-03-02 13:39:51 Local Time 1MB Download in 0.44 Seconds - 1GB Download in ~8 Minutes - 336X faster than 56K This test of exactly 51200 kB took 21.76 seconds to complete Running at % of hosts average (Suddenlink Communications) User Agent:: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:10.0.2) Gecko/20100101 Firefox/10.0.2 [!] So here's the real kicker: With all other network config the same, the iPad is consistently getting 50% BETTER throughput than my MacBook Pro. And a sidenote TestMy.Net bug report: If your logs show (and I think they do) a 257Mbps result, it's mine and it's an error. It was inadvertently produced by PageBack over the DL Test Url. Delete the result so it doesn't skew the integrity of the test result history. Quote Link to comment Share on other sites More sharing options...
