Definitely won't shoot you for that, as it's basically true, on the WMS
side of the fence. Pure WMS speed has never been the highest priority,
since MapServer does it so well. And indeed we held off on doing any
WMS for a long while. GeoServer has focused more on nice looking
production of complex styles (with anti-aliasing, ect.). And more
recently we've focused on making tiles, for use with OpenLayers,
leveraging TileCache to make the end result work faster, even if the
dynamic generation is slower. See http://sigma.openplans.org for an
example. Though it still needs to be re-cached with our latest tiling
improvements - am waiting for 1.5.0 when we can do the raster background
on GeoServer as well (the demo is currently using MapServer behind
TileCache for the Blue Marble background).
Putting up this demo server has exposed a few scalability problems, all
of which have been fixed. There are likely a few more lurking - we're
planning on doing some serious load testing ourselves, but with 1.4.0
we've eliminated all that we could testing with the resources we have.
But we're hoping to test with some more serious systems relatively soon
to work out the last remaining kinks.
