OK thanks Andrea
I understand then that the JPEG-Turbo extension would also give a boost
in this situation where I have a simple map with light vector data, right?

For a complex map normally the split is roughly 1/3 each divided among
data loading,
painting, and output encoding, but yes, for simple maps that do not
have much
to load or draw PNG encoding will surely be the slowest part,
unfortunately PNG is both
heavy to produce and to read, but it's the best option at the moment
if you're drawing
vector data.
For imagery go JPEG instead, which is already significantly faster,
and if you want
an extra boost, upgrade to GeoServer 2.3.0 and install the JPEG-Turbo
extension:
