Bandwidth Test Results
Yesterday and earlier today we did a test of the bandwidth of the download server on scripting.com. I asked people with fast net connections to download an approx 1MB file, and if they got more than 10K per second throughput, to let me know.Background: We usually hear from people who have problems downloading, and this led us to wonder if everyone was having problems. It's pretty clear that at least some people are getting our files at a reasonable rate.
Anyway, here are some of the reports...
Bandwidth Test Results
1. I am in Edmonton, Alberta Canada, using a Motorola CyberSurfer cable modem through our local cable company (Videotron). I was getting anywhere from 16 to 22 KB per second on the file which took about 50 seconds to download.
2. On my @home cable modem, I got the file at a final rate of 31Kbytes/sec
3. Took me about 10 seconds (rough guess) speed started at 17k/sec, and steadily increased to about 40k/sec by the end. cable modems are nifty.
4. I consistently got ~60K/sec when downloading the test file.
5. Here at Williams, over our T1, I got a max transfer rate of 27.5K/sec, using WinNT/MSIE 4.0. It ramped up, after sticking for a while around 17K/sec.
6. First download was at 35k. Second download hit 42k.
7. I got a 11K per second final download speed downloading the file according to IE 4.0p1. I have a Netopia ISDN router and both B channels were open during the download.
8. I'm on 2 channel ISDN. I got file at an average rate of 13KB/sec, peaking at 16KB/sec.
9. During three tries, I got on average 30 kbps.
10. I got 27k/sec receiving this file on a 31200 connection. Do you want to know why? Hardware compression.
11. Source: Rice University, Houston, TX. A pretty fast connection, considering we own and operate SESQUINET, an ISP for other companies and educational institutions. Throughput? average 6.3K/s.
12. I downloaded you file and averaged about 15k a second. I was on a T1 that only gives us 128k of actual bandwidth (the net effect is a little faster than a 128k ISDN).
13. 21k / sec, from inside the MS firewall.
14. I get 13.5K per second, basically the limit of my ISDN connection.
15. I got throughput of 15K per second. Not bad for a transatlantic connection...
16. I'm on a cable modem and got about 20-25 K/s.
17. I was able to receive the testfile at between 10.3K and 12.3K/sec, here at Nortel.
18. Dave, I had roughly 12k per second when downloading the test file. Sometimes a couple tenth's more, sometimes less. I am, however, only in Santa Cruz, and it's 1:11 AM. Things to consider.
19. I got around 15K/sec right across the Atlantic.
20. We've got a T3. I downloaded your test file and it peaked at 45K per second.
21. File came across dedicated 128K ISDN at 52-54K on Friday at 8:20 AM CST here in Austin.
22. I averaged about 60-70 KB/Sec while downloading your test file @ 9:20 AM ET, 05 Dec 97. Brief peak over 100 Kb/Sec.
23. I downloaded your test file and though throughput was under 10k/s at the start, about a third of the way through it started climbing and stayed in the low 30's for the whole last half. I'm in Boston; we have a T-1 to UUNet, if that helps.
24. Downloaded file at approx 70k/sec on a T1 line.
25. Hi Dave. I averaged 30k per second at 8:25 AM central standard time, friday morning. I am on a T1 in Nashville, TN.
26. Connected via T-1 and downloaded at 30+K/sec.
27. I downloaded the file at 9:32 a.m. Eastern time and averaged more than 60K a sec. We're connected thrugh a t-1 line.
28. I got the file at 13.2k/s...
29. Through FedEx's multiple T3's (I think?) and proxy server(s), I got 65-67KB/second using Netscape Communicator 4.04 for HP-UX 10.20.
Once the proxy had cached it, it was at least three times faster than that (on both my Unix and NTW boxes), but that's not helping you with Internet bandwidth.
One extra tidbit on firewalls: many, MANY Java applets do not work through them. Write once, run somewhere. You can't guarantee where unless it's an Intranet application, and even then, incompatibilities remain.
30. Averaged about 18K per second.
31. Speeds of between 27 and 30 kps (as reported in netscape 3.01) - shared T1 and 166 mhz pentium pc, pci 3com ethernet card. It's 9:39 am est and the network here is not too busy.
32. Reached 38k/second to houston at 834AM CST.
33. Using a T-1, I was able to get upper 20's low 30's.
34. I got throughput of 15-20K/sec. I'm on a (gag, barf) token ring network with some segments on fast ethernet.
35. At 10:02 AM EST, here at Princeton University, on a PowerMac 8500/180, running Netscape 3.04. I dragged the link to the desktop, and Netscape displayed a download window almost immediately. Though I didn't have a stopwatch handy, Netscape's display varied between 11.3 and 12.6 kb/sec.
36. I ran your bandwidth test. I am on a T1 line here at my work and got a peek speed of 17.5k per second. I'm not exactly sure what the average rate was but it was definitely more than 10k.
37. I downloaded your test file, and the download was on the order of 50K/sec.
38. I tried the bandwidth test just a few minutes ago. The throughput rate varied from 10.6 to 13.4 kps. I was a little surprised because our tech people tell that the lines out of MU start to clog about 8am. I always do large downloads before 7:30am.
39. 11.0 k/sec on an ISDN connection..
40. The file came across correctly. I averaged around 30K per second.
41. The Netscape 3.04 FTP box fluctuated over 60K mostly, under a couple of times.
42. I got 66Kbps at work.
43. I got transferspeeds from 20K/sec to 44K/sec on the test file, mostly hovering around 35K. We have a t1 (currently stopped down to 512kbps to save a little money). We use a regional ISP, Intercom Online, which has no dialup customers. UUNet and MCI backbones.
44. I downloaded your test file at ~55K per sec, T-1 connection to Mac Communicator 4.04.
45. I got 48k/sec over our extremely fast backbone.
46. My transfer peaked at 25.5K per sec.
47. Downloaded using Netscape4 on WinNT4 running on a Dell PPro200 machine. (our LAN has a T1 through Netcom in NYC) Speed number kept increasing through the life of the download, hitting around 40kb/s at the end...
48. Just tried to download the file, testfile.zip and I only averaged 7K per second. It did reach as high as 8 but generally was 7. I'm on a T3.
49. Downloaded from our T1, 11:00 am Eastern time. I got between 35-40K per second. Not blazing (I can regularly get 120K/second from Netscape's servers), but respectable.
50. I got about 53k per/sec dl'ing this file. It unzipped without a problem.
51. I got between 86 and 100k/sec from my homebuilt PC on the Stanford Univ. campus Ethernet.
52. I downloaded your test file and achived a rate of 20.2K/sec. Hope that's a satisfactory number for you. The route was probably CA -> Boston (our corporate tie to the internet is there) -> Chicago (via our 56K link to our Boston HQ).
53. I got upwards of 90KB/sec
54. Tried you download test, got avg. throughput in the mid 20kbps range, peaking at 31.2Kbps, using Netscape 4.04 on Win95. I'm wired to a 10BT network on the ASU campus network. The best througput I've ever got here was probably about 60kbps, and typically it is 10kbps or lower from the web (and rarely even 1kbps from microsoft. Go figure.
55. I got 55-60 KB per second in three attempts.
56. I downloaded the file at 11:50 EST on 12/5 on a T-1. The connection time started at 1.2k/sec but steadily rose to 12.5k/sec by the end of the download.
57. just download the test file...got a steady 70-72K/sec. T-1 Here to PowerMac 7600/200. 10BaseT EtherNet. 12/5/97 at 9:00 am PST
58. I got ~35k/s (M*Power 200, 10Base2 Enet connection, Netscape 3).
59. I downloaded your test file. It started slowly, but one it got going, throughput was 24.8K/sec. I'm on a corporate LAN connected to the Internet via multiple T3s.
60. I downloaded the file at 67.7K from here at Be.
61. We've got a fairly fast line into the BCTEL HQ building up here in Vancouver, so I thought i'd download your file.
I tried it three times: The first time, I achieved a paltry 7.3 Kbps sustained rate. I'm still just getting used to a windows machine (I come from a mac-based photography and graphic design background - and i'm finding the switch tough!) and i've noticed that if i've got lots of stuff open at once and I leave the machine long enough for the energy-saving mode to kick in, when I wake it back up, it's quite sluggish, and i'm eventually forced to restart it.
Anyway, that seemed to be the case here - after restarting, I downloaded the file, and reached a sustained transfer rate of 77.0 Kbps, followed by one last test at 85.0 Kbps.
62. Dont know if you're still accepting submissions, but here goes. got 60-70k/s on stanford's T3 network. not bad, i sometimes get up to 600k/s within stanford, and about 250-300k/s with other major sites (netscape, mit, harvard...)
63. I downloaded your test file. Top speed 40.1k/sec. average speed was between 32-35k/sec.
64. I downloaded the file from via my company's Internet connection at around 50K per second.
65. In MSIE 3/Mac I got 40-43 KB/sec.
66. Opera 3.0 b8 downloaded the test file so fast that by the time choose a place to save the file to, it had completed the download! I estimate around 90 kb per second. I have a P-166 operating from within the Netcom firewall.
