Re: Dial-up is better, faster... Could be, but keep in mind that I'm going from the whole city's records on speedtest.net, and AFAIK they measure non-latency-based stats. I've seen upload vary greatly on the connection in fine weather at the dish location..dunno, but it seems like sat is very, very YMMV'y. Better than dialup, yes. Better than anything else (but maybe 2\2.5G cellular)? Probably not. |

| Speedtest.net doesn't measure upload speed accurately* for my wildblue connection (*when I say accurately, I mean it doesn't measure the maximum speed you can sustain when transferring a larger file.)
vs testmy.net:
![]()
:::.. Upload Stats ..:::
Upload Connection is:: 234 Kbps about 0.2 Mbps (tested with 2992 kB)
Upload Speed is:: 29 kB/s
Tested From:: »testmy.net/ (Main)
Test Time:: 2008/07/20 - 4:09pm
Bottom Line:: 4X faster than 56K 1MB Upload in 35.31 sec
Tested from a 2992 kB file and took 104.603 seconds to complete
Upload Diagnosis:: Awesome! 20% + : 47.17 % faster than the average for host (wildblue.net)
U-Validation Link:: »testmy.net/stats/id-EZTP2R7S9
User Agent:: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1 [!]
The testmy.net mirrors what I get if I upload a larger file via ftp as reported by the ftp software or if I upload files via the web to print at kodakgallery or a commercial printer, etc.
Via ftp, if I transfer little files due to the traffic shaping and latency, they go at about dialup speeds *but* I set FileZilla to do 8 concurrent transfers at once which works great to better utilize my wildblue upload bandwidth.
(the speedtest.net site does measure spot-on for my DSL connection comparing almost exactly to what I get real-world, so I think it's either the latency or test file size in their upload test that measures something different than the maximum sustained speed I get over satellite.)

| Hmm, I believe the Speedtest.net test uses a packet stream for the test, whereas testmy.net uses a file. Something like that.
Anyhow, I read awhile back in some PDF that sat modems tend to tamper with TCP protocols (spoofing of something or other) and thus, while real-world results are better, stricter tests get abosolutely botched.
So basically satellite's only advantage over dialup is in dealing with large file transfers. Realtime applications just don't work right, which is fair enough when you look at latency and such.
Guess I'll test that WB connection again using some file-based speed testers. The packet-based ones tell me what I already know: this thing ain't gonna do VoIP. Thanks for pointing that discrepancy out. |
