Got the picture.
Question, did you add overviews to your geotiff?.
From experience, I have been able to serve 100 geotiff (RGB) of 2gb
each by retiling and adding oveviews to each single geotiff then
using the mosaic plugin. A real pyramid is a real speed up only when
you have *may* files where many depends on the OS and on the number of
usrs you are trying to serve. Outside this "*many* files" using a
pyramid is more or less useless.
Ciao,
Simone.

Hi Simone,
Technically I probably don't need rasters. This is a university assignment
(masters dissertation actually) and it's going to be staying within the
university network. On the other hand, as it's a proof-of concept it'd be
nice to include pyramids and tiles - I'm probably going to have to write
about them in the dissertation part after all.
Several landsat scenes. They're currently 190MB GeoTiff files (composite
of three bands).
Probably various other raster datasets of varying sizes. Ideally I'll find a
dataset that covers the entire globe for a few gigs and put that in there
too (i.e. Gtopo 30 SRTM).
Even though I have an entire machine to myself acting as a server (a fast
one too!), it still takes a noticeable few seconds to render-up just the one
landsat-geotiff, so I imagine when I ask it to show me several rasters at a
time (which I will) it might start slowing a lot. That'd be the slightly
more pragmatic reason for wanting pyramids and tiles.

Ciao Jonatan,
before going down the complex paths I would ask you to stop and give
us a few information about what kind of rasters are we talking about.
I have seen many posts talking about pyramids and the like but my
experience tells that 60% of the time people don't really need them,
so, what data are you trying to serve?
Simone.
