Hi list, While trying to download software one often comes across options to use one of many mirrors to get the software. What general guideline can one follow to select the mirror site. Physical proximity obviosly does not work.
Normally one would ping the mirror sites and compare the response time. You can also do a traceroute to see the number of hops and time required to reach a host. The mirror with the smallest response time should give you the fastest downloads. But this is assuming that the network conditions remain constant and routes to destination don't change. Even after you are able to identify the nearest mirror site in terms of the response time, the mirror may have some bandwidth limits imposed on a per download basis or could be on a small internet pipe (in terms of bandwidth) so you might end up getting a faster download from a remote site which does not have any bandwidth restrictions.
Its
something to do about transatlantic cables, gateways and such but what exactly?
It will mainly depend upon your ISPs backbones i.e. how it is connected to the rest of the internet. If its using satellite connectivity its bound to be slower than an ISP using submarine fibre optic cables.
Could getting stuff off Tucows be faster when using a miror in Philipines or
Canada?
Canada from my PC at the moment !!
