[Benchmarking] 2013 Shootout?

Martin,
thanks for proposing this, I think this is a great idea.

The OpenData published by the OS is a real-world set of data from very
different geographic resources. I have been working with them quite a
bit recently and encountered some really interesting issues. For
example that a compressed raster will serve faster from a cloud
environment than an uncompressed version but that the uncompressed TIF
served form a standalone machine with much less CPU but a HD directly
connected to it will beat it by lengths.

So my interest would actually be in learning more about these options,
not which software is the "best" [1]. (I married MapServer a long time
ago and only death will separate us, sort of :-).

I'd be interested in helping to find data, create architecture /
hardware scenarios and might even provide some modest server resources
myself.

Ah, plus this will allow us to shed some light on Open Data (and I
will make sure there is some OSM in the mix to compare with OS GB, if
only for the provocative effect of having pub symbols on an
authoritative map). ...plus I am currently evangelizing or advocating
Open Data to UK Local Authorities - and showing that it is possible
and even easy with Open Source tools will make a great mix. Ahm, and
yes, that one can then even combine them with the proprietary folks in
the mix (closing the loop to Martin).

Have fun,
Arnulf

SLD files are available for all products, as far as I know.
