Re: Sure Web Based Speed Testers are accurate ! I think the real story with poor Sprint BB network performance is latency and the burstiness of their network. ftp downloads and dsl report's speed testers are both based upon downloads and uploads of large files.
With respect to performance for web browsing, VPN, gaming, and such, these types of tests are skewed, because they trigger "opening up the pipe" later in the download or upload; this is directly observable when watching an FTP download. This is also why many people observed that web surfing improved dramatically when they opened a streaming video while surfing.
Large file downloads and uploads have an entirely different traffic profile than web browsing and VPN, which are more interactive in nature and consist of lots of small packets going across the link. This is why Sprint is misleading their customers with their FTP downloads to show speeds, and why DSL report's speed tests don't tell the whole story about Sprint BBD performance.
What's a good performance test for interactive Web surfing and such? I dunno, but I somebody could probably write their own by analyzing the output of tcpdump, for example ... but that's beyond Internet 101  |
