Quick ping time doesn't mean much, unless it is very slow to respond. The bandwidth is very important.
Oh yes, how well it can keep the pipeline filled and how fast you can consume it. As I said ... I'm paying for a channel many times faster than the best perceived download speed I have experienced based on letting mirrorbrain select a site for me. While a 'ping' may tell you the electronic distance and the modified sort of ping that is 'traceroute' you are quite right, Carlos, neither tells you about bandwidth. It may be that a site in Israel give me, here in Canada, the best bandwidth and the times I carry out my downloads of updates. So, does mirrorbrain somehow figure out bandwidths? I'd love to know how! There are many mirror sites. While pinging then to find 'distance' may be tedious, it could be automated. And yes we know that electrical distance and physical distance are not necessarily related. But other than just hitting on one well performing site as Fraser_bell describes is, well ... those of who know optimization theory recognise that this may just be a local maxima and there are 'higher peaks' out there. But how to find them? even if, as Fraser_Bell mentions, I let mirrorbrain select and note the local optima, I still don't now why it selected that site at that time and another poorly performing site at another time. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
