I dont mean to use this blog as a board to review which is faster - DSL versus Cable. But definitely I did do some benchmark tests to find out which is faster DSL or Cable. And I could not resist blurting that out at my blog. I have been a SBC DSL customer for the past 1+ year. I had a promotional rate of 26 dollars + hidden taxes for the first one year. Since November I have been paying almost 60 dollars for my internet and phone bills...basic phone service with caller ID and SBC DSL (1.5 Mbps down and 256kbps upload). As a move towards reducing my internet costs, i decided to order cable internet and finally got basic cable TV + high speed internet from Comcast (local cable provider). The free cable modem (leased from Comcast for 3 dollars per month) didnt seem to work properly (long story) and Comcast was ready to send a technician to fix it for 50 dollars. I told them to "scr3w y0urs3lf" and went ahead and bought a cable modem from a local store.
The new cable modem from the local store did an awesome job and tonight i am a proud owner of two internet connections - Comcast Cable and SBC Yahoo DSL. I decided to use some bandwidth testers to measure download and upload speeds. Here are the test results..
Test Setup:
3.4 Ghz Intel CPU running Windows Media Center edition 2005
1 Gig ram
10/100 nic connected back to back to Cable modem for Cable speed tests
10/100 nic connected back to back to DSL modem for DSL speed tests
Test Results:
Test no 1: SBC Yahoo DSL has a online tester. I used the service to test both my DSL and Cable internet connection.
DSL -
Download speed - 1111 kbps
Upload speed - 306.98 kbps
Cable -
Download speed - 1669 kbps
Upload speed - 367.81 kbps
It looked like there is not much difference between both the flavours. So I decided to use another website and after much googling found a website which seem to perform much better with bandwidth measurements. Read more about it at Test no:2.
Visit "testmy.net" website to perform Upload as well as Download measurements. The unique feature with this website is that they measure bandwidth with different file sizes.
Cable : Download tests (Speed of connection/File Downloaded at)
Test 1: 3098 kbps/378 KBPS (Kilo Bytes per second)
Test 2: 2737 kbps/334 KBPS
Test 3: 2474 kbps/302 KBPS
Cable : Upload tests (Speed of connection/File Uploaded at)
Test 1: 361 kbps /44 KBPS
Test 2: 362 kbps / 44 KBPS
Test 3: 361 kbps / 43 KBPS
Conclusion : Cable seems to have an average Download speed of 2.5-3 Mbps and Upload speed of 364 kbps
DSL : Download tests (Speed of connection/File Downloaded at)
Test1: 1306 kbps / 159 KBPS
Test2: 1210 kbps / 148 KBPS
Test3: 1302 kbps / 159 KBPS
DSL : Upload tests (Speed of connection/File Uploaded at)
Test 1: 284 kbps / 35 KBPS
Test 2: 286 kbps / 35 KBPS
Test 3: 284 kbps / 35 KBPS
Conclusion: DSL seems to have an average Download speed of 1.2-1.3 Mbps and Upload speed of 284 kbps.
Test no 3:
A simple file download of 8 mb in size took 18 seconds on an average (based on 3 successive tests) via Cable modem.
The same file download (8 mb) took 50 seconds on an average via DSL modem(based on 3 successive tests)
Definitely Comcast cable is outperforming SBC DSL in download speeds. Upload speeds are failry the same. After all this blog did become a benchmarking arena for Cable vs DSL.
