[mapserver-users] MapServer on Intel Atom?

Hi Jukka, actually I'm quite surprised, because based on my experience, raster layer is always slower than vector layer regardless of system. I attached  the gdal info result with this mail.

And Milo, yes, I have both MapServer and browser running on my notebook. The browser accesses MapServer using localhost connection. I'm interested in your idea though. Do you mean I can create a web-based interactive map solely using ogr and gdal, without MapServer component? But how? Is it possible for a web application to interactively display .SHPs and .TIFFs without MapServer?

Or do you mean I have to stay connected to the internet (to access the remote MapServer) during my demo? Unfortunately, in most cases  I won't be able to connect to the internet during the demo.

Nonetheless, is MapServer more CPU-dependent or memory-dependent? How far large RAM can compensate for weak CPU like Intel Atom?

Thanks,
