Just out of curiosity,

With what reason would you like to have a mapserver on a mobile device? I assume mostly to have some sort of localhost connection from a local application, and in that case, I would opt for a solution where one can for instance download raster-tiles from a server to the mobile device that are then used by the application through more simplified functions, for vector the same procedure, download vectors and make them available through libraries. Installing a httpserver with mapserver as a cgi app sounds like a bit of overkill. Perhaps the mobile app can simply use gdal and ogr libraries.

Hi,

You say that your raster layer is slower than vector layers, but do you feel it is too slow? Your image should be served pretty fast by Mapserver. The key is that tiff file is tiled (for zoom-in situation) and that it has overviews (for zoom-out case). Could you send the gdalinfo report about your image if you suffer from slowness?

Hi, thanks.

The vectors are quite simple. I've never experienced slow down when displayed vector data, not even on an old Toshiba M20 laptop.

Raster, on the other hand, is always the biggest problem. Compared to polygons, my raster is always slower to zoom, to pan, etc (despite the size is only 500 Mb). Is displaying raster more CPU-intensive or memory-intensive? If I'm using Intel Atom, will my raster be affected severely?

Also, can using bigger RAM (let say, 2GB or so) compensate for the lack of processing power of Intel Atom?

Thanks again,
-Kresh

will be more
than adequate... depending on the dataset. :-)

Serving 100 points is significantly less intensive than serving 100 city-boundary polygons.

Subject: [mapserver-users] MapServer on Intel Atom?

I'll be doing a lot of MapServer demo in the
future. I'm quite interested in
Intel Atom-based subnotebooks for the purpose (like
Lenovo IdeaPad S10), since
they are light and mobile.

However, I wonder if Intel Atom is adequate to run
MapServer. The MapServer will
be run on either ms4w on Windows XP, or directly on
Linux. The layers are stored
on postGIS (there are fifteen layers or so), and there
is also a 476 megabytes
raster file in .TIFF format.

Will Intel Atom be adequate for the purpose? Will 2GB
of memory help? Has anyone
ever done such thing before?

Many thanks,
-Kresh
